## When do Adata media come to us?
Adata is a distinctive brand in the storage market. Unlike Western Digital, Seagate or Toshiba, it is not primarily a hard-drive manufacturer—its core lies in system memory, SSDs and flash. This is reflected both in the kinds of devices Adata arrives at the lab with and in what their recovery looks like. Adata external drives do not contain a hard drive of Adata's own making, but a hard drive from another manufacturer (most often Toshiba, Seagate or WD; on older units, other brands too), whereas the SSDs and flash are Adata's own product. The recovery procedure therefore differs depending on the type of media.
Typical situations, broken down by device type:
#### Adata external hard drives (HD710 Pro, HD650, HV620S and others)
- **A drive after a drop or impact**—even on the rugged HD710 Pro line, which carries an IP68 rating and meets a military drop-resistance standard, the protection mainly shields the enclosure, not the drive inside. After a drop, do not connect or power the drive—if the read heads inside were damaged, every further spin-up can extend the damage.
- **Knocking, clicking, the drive won't spin**—because inside the enclosure there is a 2.5" hard drive from another manufacturer, these are the same mechanical faults as on any 2.5" drive: damaged read heads or data platters, stuck heads (stiction), motor or bearing failure.
- **The drive is no longer recognized after a power surge or with a faulty USB**—the cause is often a broken or damaged USB connector or a faulty USB bridge in the enclosure, but a surge can also hit the electronics (PCB) of the hard drive itself. Outwardly these states look the same; exactly what failed is only revealed by diagnostics.
- **A damaged rugged enclosure**—the rugged models (HD710 Pro, HD330) have a multi-layer construction with a silicone shell and a damping layer. After an extreme impact or flooding, the enclosure has to be professionally disassembled without damaging the drive or the connector inside.
- **The drive is visible but reports as empty, RAW or asks to be formatted**—a logical fault. The file system can be damaged by an unsafe disconnection or a power loss during writing, by bad sectors, an interrupted format or malware. This also includes the case where a drive formatted for Apple (HFS+/APFS) is connected to Windows (or vice versa)—the data is fine, the system just cannot read it. Accidentally deleted files or a performed format belong here too.
#### Adata SSDs (XPG Gammix, Legend, the SU line, external SE)
- **An SSD suddenly vanishes from the system or does not appear in the BIOS**—a common type of SSD failure. The cause is usually a failure of the controller's service data, often as a result of defective memory cells that corrupt the service data. The drive then reports zero capacity, an incorrect model designation, or switches into an emergency ("safe") mode. Sometimes, by contrast, it reports correctly but stays inaccessible on read ("busy") or returns empty sectors as if it had been wiped.
- **The SSD is visible but extremely slow or returns read errors**—degradation of NAND cells, a growing number of bad blocks, or a problem with the mapping (translator) between logical and physical addresses.
- **An external USB SSD (SE800, SE900G, Elite SE880) is unresponsive**—inside is an NVMe or SATA SSD module with a USB bridge. The bridge can fail, the SSD module itself, and on some models hardware encryption also plays a role (more in the specifics section).
- **An SSD after a power surge or overheating**—damage to the controller or the power section on the PCB.
- **The SSD is visible but reports as empty, RAW or asks to be formatted**—a logical fault (a damaged file system, deleted or reformatted partitions). On SSDs there is added urgency: after a delete or a format the controller can quickly discard the data (TRIM), so stop using the media immediately.
#### Adata USB flash drives and memory cards
- **A flash drive is not recognized or reports zero capacity**—the cause is often a controller failure, but also defective NAND memory cells. If the problem is in the controller, the data remains in memory and it is a matter of regaining access to it.
- **Mechanical damage**—a broken USB connector, but also a flash drive or card that is snapped or crushed. Depending on the media's construction and whether the memory chip itself is damaged, the recovery procedure varies.
- **An SD or microSD card is unreadable**—the card reports as empty, RAW or asks to be formatted. On compact cards where the controller and memory sit in a single potted chip (a monolithic construction), this is a specific recovery case.
- **Accidentally deleted files or a performed format**—on classic flash drives and SD cards, deleted data usually remains physically intact until you overwrite it. This is not always the case, though: some devices reset the internal mapping on format, and some cards and flash drives today can discard deleted data (TRIM/UNMAP)—after which logical recovery may no longer be possible.
## Adata lines and models we work with
Adata has a broad portfolio across storage categories. Alongside the main brand there is the gaming sub-brand **XPG** (Xtreme Performance Gear), which covers the higher-performance SSDs and memory. For data recovery it is useful to break the portfolio down by media type, because each one requires a different procedure. Below we list the most common lines from roughly the past 15 years—we also see models not listed here.
#### External hard drives—HD710 Pro, HD650, HV620S and others
Adata external 2.5" hard drives powered directly over USB. The key thing for data recovery: **Adata does not make hard drives itself**—inside the enclosure is a 2.5" hard drive from another manufacturer, most often Toshiba, Seagate or WD (and on older generations, other brands too). Once removed from the enclosure, the recovery procedure is governed by the specific drive inside.
- **HD710 Pro / HD710 / HD710M Pro**—the flagship rugged line (IP68, drop resistance per MIL-STD-810G), triple-layer construction. Capacities 1–5 TB, USB 3.2 Gen1. Inside is a 5400 RPM 2.5" hard drive (typically Toshiba); the USB bridge is usually an ASMedia chip.
- **HD770G**—a newer rugged model with RGB lighting and an IP68 rating.
- **HD330**—a slimmer rugged drive with shock protection, capacities up to 5 TB.
- **HD650 / HD680 / HD720**—the DashDrive Durable anti-shock line with a rubberized or silicone surface.
- **HV620 / HV620S / HV320**—the slim line without a rugged shell, a thin enclosure.
- **DashDrive Durable, NH13** and other older 2.5" external drives (from roughly 2011 onward).
The enclosure architecture varies between generations. On some models the USB bridge is a separate board to which the drive is connected over a standard SATA interface—once removed, it can be connected directly. On others the bridge is more closely integrated. The rugged models additionally have a silicone shell and a damping layer that must be professionally removed when opening them.

#### Internal SSDs—XPG Gammix, Legend, the SU line
The core of Adata's products. Here it is already Adata's own product, built on controllers from three main suppliers: **Silicon Motion, Realtek and InnoGrit**. The controller type determines the recovery procedure.
**NVMe (M.2) SSDs:**
- **Legend 970 / 970 Pro**—the flagship PCIe 5.0 NVMe line (3D TLC, DRAM cache). The 970 Pro uses an InnoGrit IG5666 controller, the 970 a Phison E26 (PS5026-E26).
- **Legend 960 / 960 Max**—PCIe 4.0 NVMe with a DRAM cache (Silicon Motion SM2264; on some production batches the controller differs).
- **Legend 850 / 840 / 800 / 710 / 700**—the mid-range and entry-level PCIe 4.0/3.0 line. The Legend 850 uses the Silicon Motion SM2269XT (without DRAM); the Legend 800, depending on the production batch, the Realtek RTS5772DL or Silicon Motion SM2267XT (QLC, without DRAM, HMB).
- **XPG Gammix S70 / S70 Blade / S50 / S50 Lite / S40G / S11 Pro / S11 / S10 / S5**—gaming NVMe of several generations (InnoGrit, Silicon Motion and Realtek controllers). The S70 Blade uses the InnoGrit IG5236 (Rainier) with hardware AES-256 encryption.
- **XPG SX8200 Pro / SX8200 / SX8100 / SX8000 / SX7000 / SX6000 / SX9000 / SX8800 Pro**—the older PCIe NVMe line. The SX8200 Pro and SX8100 on the Silicon Motion SM2262EN/SM2262G with DRAM.
**SATA (2.5" and M.2) SSDs:**
- **SU900 / SU800**—higher-performance SATA models (Silicon Motion SM2258 with DRAM). The SU900 uses 3D MLC, the SU800 3D TLC.
- **SU760 / SU750 / SU650 / SU635 / SU630**—the entry and mid-range SATA line, mostly without DRAM (SM2258XT, SM2259XT, Realtek or Maxio depending on the batch), TLC or QLC.
- **XPG SX950 / SX930 / SX910 / SX900 / SX300**—the older higher-performance SATA and mSATA line.
- **Premier Pro SP920 / SP910 / SP900 / SP800 / SP550 / SP300, Premier SP610 / SP580**—older SATA models (Marvell, SandForce and other controllers).
- **S511 / S510** and similar—the oldest Adata SATA SSDs (roughly 2011–2013); we occasionally see them as older patients.
Note: across individual capacities and production batches of the same model, Adata occasionally changes both the NAND supplier and the controller revision. We therefore always verify the specific controller during diagnostics, not from the commercial name.

#### External USB SSDs—SE800, SE900G, Elite SE880, SD810
Portable Adata SSDs with a USB interface. Inside is an SSD module (NVMe or SATA) connected to USB through a bridge (typically an ASMedia chip).
- **SE800**—a rugged portable SSD (IP68, drop resistance), USB 3.2 Gen2. Inside is an NVMe module (InnoGrit IG5208) with an ASMedia ASM2362 bridge. Optional hardware AES-256 encryption.
- **SE900G**—a portable SSD with RGB lighting, USB 3.2 Gen2x2.
- **Elite SE880**—a very compact SSD, USB 3.2 Gen2x2, speeds around 2,000 MB/s.
- **SD810 / SC685 / SE770G / SE760 / SE730 / SE720**—further portable USB SSDs of various generations.
Note: the presence and type of encryption differ from model to model on external SSDs—which is why we return to it in the recovery specifics section.
#### USB flash drives and memory cards
- **USB flash drives**—the UV (UV128, UV131, UV320, UV350…), S (S102 Pro, S007…), C (C008, C906…), UE (UE700, UE800…) and DashDrive lines.
- **SD and microSD cards**—the Premier, Premier Pro, Premier ONE and High Endurance lines. On higher capacities and compact cards this is often a monolithic construction (controller and memory in a single potted package).
#### Adata as a brand
Adata Technology was founded in 2001 in Taiwan; it began with system memory (DRAM) and gradually expanded its portfolio to flash and SSDs. The gaming sub-brand XPG targets the performance segment. For data recovery the point made above is essential: **Adata is not a hard-drive manufacturer**. External HDDs under the Adata brand are enclosures fitted with a hard drive from another manufacturer, whereas the SSDs and flash are Adata's own products built on third-party controllers (Silicon Motion, Realtek, InnoGrit). This distinction determines the procedure by which data is recovered.
## What to do when you lose data or an Adata device fails
The procedure differs by device type and by whether it is a physical failure or a logical fault (a damaged file system, deleted data, an accidental format). Several principles, however, are universal and determine the chance of a successful recovery:
1. **Disconnect the device and do not keep reconnecting it.** This applies to hard drives (HDD), SSDs and flash alike. On a mechanical drive, every further spin-up can extend the damage; on SSDs and flash, needless reconnection triggers internal operations that can make things worse.
2. **If an external drive knocks, clicks or won't spin up—do not try to start it again.** Inside is a classic 2.5" hard drive, and mechanical noises are a typical indicator of damaged read heads. Repeated start-ups can lead to scratched platters and a lower chance of recovery.
3. **Do not run chkdsk, format or recovery software** if the media reports as empty or asks to be formatted. These tools can overwrite data or structures that would otherwise be recoverable.
4. **If the media reports as empty, RAW or "to be formatted," do not panic and do not format.** Sometimes it is a trivial matter—for example a drive formatted for Apple (HFS+/APFS) connected to Windows, which shows it as unformatted even though the data is fine (and vice versa). Other times the file system really is damaged—after an unsafe disconnection or a power loss during writing (exFAT, which has no journal, is especially vulnerable), through bad sectors or memory cells, an interrupted format or malware. In the vast majority of cases, though, the data remains on the media—formatting or further writing can overwrite it.
5. **On SSDs, do not try the manufacturer's "repair" tools or a secure erase.** If an SSD has dropped out of the system, any write or attempt to reset the firmware can irreversibly destroy the data.
6. **Do not try to repair or resolder a mechanically damaged flash drive or external drive yourself (a broken USB connector, a cracked housing).** On flash drives and cards you risk damaging the memory chip or the controller; on drives, damaging the electronics.
7. **Do not disassemble a rugged drive after flooding or dry it at home.** The multi-layer enclosure requires professional disassembly; an amateur attempt can damage the drive or the connector inside.
8. **Myths that have no effect or are outright harmful:** putting the drive in a freezer, drying it in rice, repeatedly reconnecting it in the hope that the device will spring to life. They have no real technical basis and in some cases cause damage that would otherwise not have occurred.

## Adata data recovery specifics
Because Adata covers several different storage types, there is no single universal procedure. The following sections summarize how recovery differs by media type.
#### External drives: a hard drive from another manufacturer
The key specific of Adata external drives is that inside the enclosure there is a 2.5" hard drive from another manufacturer (most often Toshiba, Seagate or WD). Once removed from the enclosure, data recovery is effectively recovery from that specific drive—governed by its manufacturer, generation and fault type. This has a practical consequence: the know-how and the workshop base (donor parts) for the given drive are the same as for any 2.5" drive.
In technical detail
On a mechanically damaged drive (damaged read heads, a seized motor), the standard procedure is to replace the damaged component with a part from a donor drive of exactly the same family and firmware revision, performed in a cleanroom. From the repaired drive we then create a binary (bit-for-bit) copy, and only from that copy do we recover the data—the original is no longer worked with. On rugged models it is additionally necessary first to professionally remove the silicone enclosure and the damping layer without damaging the USB connector or the drive.
A separate category is electronics failure after a power surge or a short circuit—typically through a faulty USB port on the computer or a damaged cable. A surge may damage only the USB bridge in the enclosure, but it can also hit the electronics (PCB) of the hard drive itself and, in some cases, its internal electronics in the read-head assembly. If only the bridge failed, the solution is the simplest one—once removed, we connect the drive directly over SATA. Merely swapping the drive's PCB for a board from another unit, however, does not lead to the data, because almost every hard drive stores unique adaptive service data in two places: in the ROM chip on the PCB and in the service area on the data platters. Recovery therefore requires reprogramming a donor board with the contents of the original ROM, or in some cases transferring specific chips. On the newest drives, moreover, part of the adaptive data is integrated directly into the main chip (MCU) tied to that specific drive—then even swapping the board with a transferred ROM is not enough and the procedure is handled individually. We perform this work with PC-3000 technology. Exactly what the surge affected is determined by diagnostics.
Note: the 2.5" drives inside current external drives may use shingled SMR recording, which has its own specifics for recovery. If an Adata external drive reports as empty or returns zeros, this may be exactly that case.
Logical faults are also common—accidentally deleted files or a performed format. On the hard drives inside external enclosures, the write technology matters here: on classic drives (CMR) deleted data is usually recoverable, while on shingled (SMR) drives the situation is more complex and recovery depends on the specific generation. We cover these specifics in detail on the hard-drive data recovery pillar.
→ **Detail:** [Data recovery from hard drives (HDD)](https://www.exalab.cz/index.php?option=com_content&view=article&id=72:data-recovery-from-hdd&catid=2:zachrana-dat&Itemid=711)
#### SSDs: controller, firmware and translator
On SSDs, faults fall roughly into two groups that often overlap. The first is **a failure of the controller's service data** (the translator, mapping tables, firmware modules), where the NAND memory with the data stays fine but the controller has lost the ability to read and assemble the data correctly. The second, no less common, is **defective NAND memory cells**—their wear or failure very often also corrupts the service data stored on the NAND, and thereby disables the controller. In practice we therefore address both on SSDs, often at the same time.
If the fault lies in the controller or service data, the procedure depends on the specific controller (on Adata, Silicon Motion, Realtek or InnoGrit):
- **Switching the controller into a technological mode**—a service mode in which the firmware and service data can be worked with below the level of ordinary user access.
- **Loading the service loader for the given controller family** and repairing or regenerating the damaged firmware modules.
- **Reconstructing the translator**—the mapping between logical addresses (LBA) and the physical location in NAND. Without a functional translator, the drive returns zeros or unreadable data.
- **Controller emulation** in cases where the controller itself is irreparably damaged and its function has to be replaced.
If the cause is defective memory cells, the procedure differs or is combined with the above—the damaged blocks have to be bypassed and the data reconstructed even from partially readable memory. With deleted files or a performed format it also holds that if the controller has already discarded the data (TRIM, garbage collection), logical recovery may not be possible; in some cases we reach the deleted data only by working with the service data. Diagnostics will show the specific chance.
In technical detail
On most modern SSDs, so-called chip-off recovery (desoldering the NAND chips and reading the memory directly) is ineffective, because the data is transformed at the controller level. Some Adata controllers—for example the InnoGrit IG5236 in the XPG Gammix S70 Blade line—use hardware AES-256 encryption, where the key is generated inside the controller and tied to a unique key fused into the silicon; after desoldering the chips, only encrypted data would be read. Other controllers (for example the SATA Silicon Motion SM2258XT, SM2259XT) use XOR scrambling to even out the wear on NAND cells—this is not encryption in the security sense, but even so the data cannot be read directly without knowing the algorithm. On non-encrypted controllers the controller itself is usually replaceable with another unit of the same family, because the unique data is in the service area on the NAND chips, not in the controller; on controllers whose encryption is tied to the specific silicon (such as the IG5236), however, this does not hold—the key cannot be transferred, so the original controller must be revived on the original board. Even where swapping the controller is possible, in most cases it is more reliable to work with the original, repaired controller than to swap it or attempt a chip-off.
→ **Detail:** [Data recovery from SSD](https://www.exalab.cz/index.php?option=com_content&view=article&id=77:data-recovery-from-ssd-free-consultation-diagnosis-and-pickup&catid=2:zachrana-dat&Itemid=750)
#### Hardware encryption on Adata SSDs
A large share of Adata SSDs and external SSDs use hardware AES-256 encryption directly in the controller—this does not apply to all models, though, and on some it also depends on the specific firmware version, which is why we avoid absolute statements. What this means for recovery: if encryption is active and tied to the controller, it is necessary to work with the original controller, because the key cannot be transferred elsewhere. This is precisely why chip-off (desoldering the memory) is the last resort on encrypted SSDs—only encrypted data would be read. We always verify the specific state during diagnostics.
#### Flash drives and memory cards: reading NAND and reconstructing the controller
On USB flash drives and memory cards the principle is similar to SSDs, only with a simpler architecture. Here too, a common cause is both a controller failure and defective NAND memory cells. When the controller fails, recovery is done by **reading the raw NAND memory and reconstructing the controller's algorithm in software** (ECC correction, descrambling, reassembling interleaved blocks, reconstructing the mapping) in order to assemble the original data from the memory; with defective NAND, the damaged blocks additionally have to be bypassed. On monolithic SD and microSD cards, where the controller and memory are in a single potted chip, the procedure is more demanding and requires connecting at the level of the chip's internal contacts.
For work with SSDs, flash and hard drives we use a range of hardware and software technologies—alongside the **ACELab PC-3000** platform (including the PC-3000 SSD and PC-3000 Flash modules), also UFS Explorer and our own procedures and technologies developed in-house at EXALAB. ACELab is one of our suppliers, not the only one.
## Approximate cost of Adata data recovery
The final cost of recovering data from Adata media depends on the type of media, the nature of the fault and the extent of the damage. Recovering data from Adata external drives, SSDs and flash memory starts at CZK 1,500; more demanding cases (mechanical damage requiring a donor part, translator reconstruction on SSDs, monolithic cards) can be more expensive. We always set the specific price only after free diagnostics—you know in advance how much the recovery will cost, and only then do you decide whether to approve it.
Current prices for the individual media types are in the pricing list, and more detailed information about the recovery process is on the relevant pillar pages:

## Frequently asked questions about Adata data recovery
#### My rugged Adata external drive (HD710 Pro, HD330) is unresponsive after a drop. Can the data be recovered?
In most cases, yes. Even though rugged Adata drives have high enclosure protection (an IP68 rating on the HD710 Pro line, shock resistance on the HD330), this protection mainly shields the enclosure, not the drive inside. After a drop, the 2.5" drive inside (typically Toshiba) may be damaged, or just the USB connector in the enclosure—externally this looks similar, and ordinarily not even a more experienced user can tell the difference.
Do not reconnect the drive; bring or send it in for free diagnostics. **It is better not to disassemble the enclosure yourself**: the multi-layer rugged construction, and sometimes glued parts, require professional disassembly so that neither the connector nor the drive inside is damaged.
#### An Adata SSD (XPG or Legend) suddenly vanished from the system or does not appear in the BIOS. Can the data be retrieved?
Yes, in most cases. A sudden disappearance of an SSD is a common type of failure. The cause is usually a failure of the controller's service data, often as a result of defective memory cells. If the data on the NAND is preserved, it is a matter of regaining access to it; if part of the memory is also damaged, we address both at once.
Recovery is done by switching the controller into a service (technological) mode, repairing the firmware and reconstructing the mapping (translator). Adata uses Silicon Motion, Realtek and InnoGrit controllers, and for the common families we have the corresponding procedures. The important thing is not to keep using the SSD and not to try "repair" tools—every write lowers the chance of recovery.
#### Does encryption on Adata SSDs prevent data recovery?
Two levels of encryption need to be distinguished. **Hardware encryption in the SSD controller**—a large share of Adata SSDs use it; if it is active, the data cannot be obtained by a chip-off, because only encrypted data would be read, and it is necessary to work with the original, repaired controller. **Software encryption of the system** (BitLocker, FileVault, LUKS)—this is independent of the drive's maker; we can read the data off the drive, but to decrypt it you need the password or key (recovery key), which you must have available.
That is also why we do not recommend experimenting with desoldering chips on SSDs. We determine the actual encryption state and the most suitable procedure during free diagnostics.
#### My Adata USB flash drive or SD card is unreadable. Will you recover it?
In most cases, yes. On flash drives and cards the cause is both a controller failure and defective NAND memory cells. Recovery consists of reading the raw NAND memory and reconstructing the controller's algorithm, and with defective memory also bypassing the damaged blocks, in order to assemble the original data from the memory.
With mechanical damage (a broken USB connector, a cracked or crushed housing), do not keep using the media and do not try to repair or resolder it yourself—you risk damaging the memory or the controller. On memory cards (especially compact microSD), it is often a monolithic construction whose recovery is more demanding, but solvable.
#### My computer wants to format my Adata external drive, or the files suddenly disappeared. What should I do?
Do not respond to the prompt to format and do not keep using the drive. This situation usually means a damaged file system or partition structure—the data is mostly still on the drive, but the computer has lost access to it. If you format the drive or write to it, the chance of recovery drops.
Disconnect the drive and contact us. Recovery in such a case is done by bypassing the damaged structure and reading the data directly—this is one of the most common and usually readily solvable cases.
#### An Adata SSD failed suddenly, without warning. Why does this happen?
On SSDs, a sudden failure with no prior symptoms is unfortunately typical. A hard drive can sometimes signal an approaching problem (for example rising error rates), but even that is not a rule—and once a drive is already knocking or making unusual noises, it is usually too late. An SSD, by contrast, can stop working from full operation without warning. The cause is both a failure of the controller's service data and degradation or failure of NAND cells—both are common and often related.
A regular backup therefore matters on all media—SSDs, hard drives, flash drives and memory cards. If a failure has already occurred, do not keep using the media and have it diagnosed—in many cases the data is preserved and it is a matter of restoring access to it; if part of the memory or surface is also damaged, we reconstruct the data from it too.

Can the data be recovered?", "acceptedAnswer": { "@type": "Answer", "text": "In most cases, yes. Even though rugged Adata drives have high enclosure protection (an IP68 rating on the HD710 Pro line, shock resistance on the HD330), this protection mainly shields the enclosure, not the drive inside. After a drop, the 2.5" drive inside (typically Toshiba) may be damaged, or just the USB connector in the enclosure—externally this looks similar, and ordinarily not even a more experienced user can tell the difference." } }, { "@type": "Question", "name": "An Adata SSD (XPG or Legend) suddenly vanished from the system or does not appear in the BIOS. Can the data be retrieved?", "acceptedAnswer": { "@type": "Answer", "text": "Yes, in most cases. A sudden disappearance of an SSD is a common type of failure. The cause is usually a failure of the controller's service data, often as a result of defective memory cells. If the data on the NAND is preserved, it is a matter of regaining access to it; if part of the memory is also damaged, we address both at once." } }, { "@type": "Question", "name": "Does encryption on Adata SSDs prevent data recovery?", "acceptedAnswer": { "@type": "Answer", "text": "Two levels of encryption need to be distinguished. Hardware encryption in the SSD controller—a large share of Adata SSDs use it; if it is active, the data cannot be obtained by a chip-off, because only encrypted data would be read, and it is necessary to work with the original, repaired controller. Software encryption of the system (BitLocker, FileVault, LUKS)—this is independent of the drive's maker; we can read the data off the drive, but to decrypt it you need the password or key (recovery key), which you must have available." } }, { "@type": "Question", "name": "My Adata USB flash drive or SD card is unreadable. Will you recover it?", "acceptedAnswer": { "@type": "Answer", "text": "In most cases, yes. On flash drives and cards the cause is both a controller failure and defective NAND memory cells. Recovery consists of reading the raw NAND memory and reconstructing the controller's algorithm, and with defective memory also bypassing the damaged blocks, in order to assemble the original data from the memory." } }, { "@type": "Question", "name": "My computer wants to format my Adata external drive, or the files suddenly disappeared. What should I do?", "acceptedAnswer": { "@type": "Answer", "text": "Do not respond to the prompt to format and do not keep using the drive. This situation usually means a damaged file system or partition structure—the data is mostly still on the drive, but the computer has lost access to it. If you format the drive or write to it, the chance of recovery drops." } }, { "@type": "Question", "name": "An Adata SSD failed suddenly, without warning. Why does this happen?", "acceptedAnswer": { "@type": "Answer", "text": "On SSDs, a sudden failure with no prior symptoms is unfortunately typical. A hard drive can sometimes signal an approaching problem (for example rising error rates), but even that is not a rule—and once a drive is already knocking or making unusual noises, it is usually too late. An SSD, by contrast, can stop working from full operation without warning. The cause is both a failure of the controller's service data and degradation or failure of NAND cells—both are common and often related." } } ] }
