Western Digital (WD) is, alongside Seagate, one of the most frequent brands we work with in our laboratory. We handle all internal product lines—Blue, Black, Red Plus/Pro, Purple, and Gold—enterprise Ultrastar drives (originally HGST), external My Book, My Passport, and Elements drives, WD My Cloud network storage, and legacy WD SSDs (Blue SN570, Black SN770, SN850X). Diagnostics is free of charge; data recovery prices start at CZK 1,500.

When do WD drives arrive at our lab?

Western Digital and Seagate are jointly our most frequent patients—by volume, we handle WD drives slightly more often than Seagate. Our work covers everything from desktop hard drives and external drives through enterprise Ultrastar storage (originally HGST) to legacy WD SSDs from the product range the brand manufactured up to 2025.

Typical situations in which WD drives arrive at our laboratory:

Mechanical damage and hardware failures

• Drive after a drop or impact—typically external My Book, My Passport, Elements. After a drop, it is critical not to connect or power on the drive; every additional attempt to spin it up can turn a recoverable situation into an unrecoverable one.
• Clicking, ticking, repeated spin-up attempts—the classic symptom of damaged read heads or, in some cases, damaged platters. Often the result of a drop, but also of wear in older drives.
• Drive does not spin up, is silent, or only beeps—stuck heads on the platters (stiction), typically in 2.5" mobile drives, less commonly in 3.5" drives; or motor failure.
• Broken or torn USB connector—typically in My Passport and Elements Portable, where the USB port is integrated directly into the drive's PCB.
• Drive is not detected by the BIOS or operating system—PCB failure or firmware corruption in the ROM chip, or in some cases more extensive mechanical damage to the read heads. Stuck heads need not always be audible, so the “not detected” symptom may have a mechanical cause without the user noticing. Newer WD drives are further complicated by SED locked PCB.
• Water, flood, fire—WD drives affected by flooding or fire are usually recoverable; the key is not to power them on and to deliver them to the laboratory as soon as possible.
• Drive disconnects spontaneously, transfers are interrupted—progressive degradation of the platter surface, bad sectors, impending failure. The same symptoms can also be caused by a mechanically or otherwise damaged PCB.
• WD SSD is not detected, or reports 0 MB capacity—controller failure on WD Blue SN570, WD Black SN770, or SN850X.

Software, user, and logical failures

• Accidentally formatted drive or deleted partition—data is recoverable in most cases, provided no further writes have been made to the drive (new OS installation, file copying).
• Deleted files, photos, or entire folders—disconnect the drive immediately and choose the next steps carefully; every additional write reduces the chance of successful recovery.
• External drive is detected but asks to be formatted—file system corruption (logical failure) or encryption bridge failure on My Book.
• Encrypted My Book or My Passport with a lost password—drives with WD Security encryption active. With some older families the password can be bypassed, with most modern drives it cannot; the specific status is always verified. If you have the password, please bring it with the drive.
• WD Red in a RAID array or NAS slows down, rebuild fails—a number of WD drives use SMR recording, which complicates RAID operation and subsequent data recovery. This applies primarily to the basic WD Red line, but also to some WD Blue models that occasionally end up in NAS units they were not designed for.
• WD My Cloud—data lost after rebuild, file system corruption—WD My Cloud network storage is handled separately; see the section below.

WD product lines and models we work with

Western Digital covers the full storage spectrum—from home desktops through NAS and surveillance systems to data centers. The breadth of product lines we work with in our laboratory reflects this scope.

WD internal drives—consumer color lines (Blue, Black, Red, Purple, Gold)

WD uses color coding to differentiate its product range. Each color corresponds to a different workload type, firmware optimization, and warranty period:

• WD Blue—general-purpose desktop, 5400/7200 RPM, capacities roughly 500 GB to 8 TB. Not designed for NAS or 24/7 operation. The most common internal HDD in standard PC builds.
• WD Black (WD_BLACK)—performance line for gaming and creative work, 7200 RPM, larger cache, 5-year warranty. In our laboratory we encounter it primarily after notebook drops.
• WD Red / Red Plus / Red Pro—NAS-optimized with NASware firmware, designed for 1–8 bay arrays and 24/7 operation. Red Pro is the 7200 RPM variant for more demanding workloads. The basic WD Red line uses SMR recording in current models as well; the Red Plus and Red Pro variants are CMR. SMR complicates RAID operation and subsequent data recovery.
• WD Purple / Purple Pro—surveillance (CCTV / DVR), AllFrame technology for write-heavy workloads, support for tens of HD camera streams per drive.
• WD Gold—enterprise-grade for servers and data centers, workload up to 550 TB/year, MTBF 2.5 million hours, 5-year warranty.
• WD Green—eco line, production discontinued in 2015 and merged into Blue. We still encounter it in older PCs.
• WD Caviar (Blue/Black/Green/Red) and VelociRaptor 10,000 RPM—older (pre-2011) naming, now legacy. We regularly handle data recovery from Caviar drives in notebooks and desktops from that era.

WD Ultrastar—enterprise and data center drives

The Ultrastar line originated with HGST (Hitachi Global Storage Technologies), which WD acquired in 2012. The HGST brand was gradually phased out in 2018, and all drives continue under WD Ultrastar.

• Ultrastar DC HC500-series (HC520, HC530, HC550, HC560, HC570)—CMR recording, helium, capacities 14–26 TB, 7200 RPM, SATA and SAS variants, also available as SED and FIPS models.
• Ultrastar DC HC600-series (HC650, HC670)—SMR / UltraSMR for higher capacities of 20+ TB, designed for object storage and backup workloads.
• Ultrastar DC HC700-series and upcoming HAMR models—energy-assisted recording (EAMR / OptiNAND); WD has announced 36 TB CMR and 44 TB UltraSMR variants for 2026.
• Older HGST Deskstar, Travelstar, Ultrastar (pre-rebrand)—still common in recovery jobs, particularly from RAID arrays and NAS units that have been in service for many years.

For data recovery from Ultrastar drives, we work with standard CMR/SMR principles and tooling for WD/HGST service data. Helium drives require particularly careful handling—breaching the helium seal during invasive intervention means the drive will no longer be reusable after recovery.

WD My Book—3.5" external desktop drives

My Book is a 3.5" external desktop drive with its own 12 V power adapter and support for WD Security hardware AES-256 encryption via a USB bridge. The encryption status, however, varies by generation—on older families (Essential, Studio, Mirror Edition) it is typically active at all times, even without a user-set password; on the current WDBBGB family of single-disk models, activation is in most cases tied to installing and configuring WD Security, and the drive may in fact be unencrypted. If the bridge fails on a drive with active encryption, the data on the drive itself is in an encrypted state and requires a specialized decryption procedure. Capacities range from 4 to 26 TB. The internal drive is typically WD Red, Blue, or (for higher capacities) Ultrastar.

The My Book Duo variant contains two drives configured as RAID 0 (factory default), optionally RAID 1, JBOD, or Span; hardware encryption via the JMicron JMS561 bridge is, according to WD documentation, always active on Duo and cannot be disabled. My Book for Mac ships formatted as HFS+. WD easystore (a Best Buy exclusive for the US market) is functionally very similar to Elements—without encryption and without WD Security.

WD My Passport and WD Elements—2.5" portable drives

My Passport is a 2.5" portable drive with capacities of 1–6 TB and USB 3.0 / USB-C. Unlike My Book, it has hardware AES-256 encryption directly on the drive (not via a bridge). This architecture simplifies some recovery scenarios but complicates others—for SED locked models, access to the data is impossible even for us without the correct key.

• My Passport, My Passport Ultra (USB-C, aluminum body)—the standard portable line.
• My Passport for Mac—HFS+ from the factory, technically otherwise identical.
• WD Elements Portable—the basic line without encryption, without WD Security software, a more affordable option.

In My Passport and Elements Portable, the USB connector is integrated directly into the drive's PCB. If the connector breaks or is damaged, it may be necessary to reprogram a donor PCB to work with the specific drive, or to perform another operation at the service-data level—this is not a job for general repair shops. See the Integrated USB connector section for details.

WD My Cloud—network storage (NAS)

WD My Cloud is a line of personal and small-business network storage units. The architecture varies by unit type:

• Single-bay models (My Cloud, My Cloud Home)—a standard WD Red or Blue drive inside an enclosure with a network interface. EXT4 file system. No RAID.
• Multi-bay models (EX2 Ultra, EX2100, EX4100, PR2100, PR4100, DL2100, DL4100, Mirror Gen 2)—Linux mdadm software RAID with EXT4.
• My Cloud Home uses a different proprietary architecture (Android / SQLite database instead of a standard file system)—data recovery requires a different approach than for the classic My Cloud models.

A frequent cause of data loss in recent years has been the forced firmware migration from OS 3 to OS 5, which left a number of units in a non-functional state (red LED, boot loop, “drive not found”). Data on the internal drives typically remains intact—we recover it by removing the drives and reading from the storage media outside the unit.

WD SSDs—status after the 2025 Sandisk spin-off

On February 24, 2025, Western Digital completed the spin-off of its NAND flash and SSD division into a separate company, Sandisk Corporation. From that date onward, WD no longer manufactures new SSDs—the entire portfolio was taken over by Sandisk. At CES 2026 in January, Sandisk announced the rebranding of the previous WD Blue and WD_BLACK NVMe lines under the new Sandisk Optimus brand (three product lines: Optimus, Optimus GX, and Optimus GX PRO); the transition to the new brand is taking place during the first half of 2026.

Older WD SSDs manufactured under the WD brand prior to 2025 are, of course, still serviced. They include:

• WD Blue—SATA and NVMe (SN500, SN550, SN570, SN580, SN5100), the mainstream line with 3D NAND.
• WD Black (WD_BLACK)—performance NVMe (SN750, SN770, SN850, SN850X, SN7100) with proprietary WD controllers.
• WD Red SA500—SATA SSD for NAS cache.
• WD Green SSD—entry-level line, production discontinued earlier.

New SSDs under the Sandisk brand are handled separately.

Technological specifics that affect data recovery from WD drives

When recovering data from WD drives, we encounter a number of technologies the manufacturer uses across its product lines that have a direct impact on the course, success rate, and cost of data recovery. Understanding them helps users see why an apparently identical symptom may require very different solutions.

SED locked PCB and locked service data

A number of more recent WD drives (both internal and external) use what is called the SED locked architecture—Self-Encrypting Drive with locked communication between the processor and the ROM chip on the drive's electronics (PCB). The ROM contains unique service data necessary for initialization and correct reading of user data. This data is unique to each individual drive.

When the electronics of a SED locked drive fail, simple PCB replacement from another identical drive does not work—the donor electronics cannot initialize the drive because they lack the corresponding service data. Data recovery in such cases requires:

• Reprogramming the donor PCB with the ROM contents from the original (damaged) drive.
• In some cases, modifying the electronics or transferring specific chips from the original drive to the donor.
• Specialized tooling for working with the drive's service area—in our case primarily PC-3000 technology by ACELab.

Without this technology and corresponding know-how, data recovery from SED locked WD drives is problematic and often impossible. This is one of the main reasons we discourage amateur PCB-replacement attempts on more recent WD drives.

External drive encryption—the difference between My Book and My Passport

WD external drives with WD Security support use hardware AES-256 encryption, but the implementation differs significantly:

• My Book (3.5" desktop)—if encryption is active, it takes place on the USB bridge in the drive's external electronics. Data is stored on the drive itself in an encrypted state. On older families and on My Book Duo, encryption is typically active at all times; on the current WDBBGB family of single-disk models, activation is in most cases tied to installing and configuring WD Security. If the bridge fails (overvoltage, mechanical damage) on an encrypted drive, the internal drive itself works, but the data cannot be read directly from it—a decryption procedure using the original external electronics or equivalent technology is required.
• My Passport (2.5" portable)—encryption is implemented directly in the drive controller (on-drive), not through an external bridge. For SED locked variants, the drive must first be unlocked via service-data intervention using specialized technology—only then can data recovery proceed.

In both cases, if a WD Security password is active and the password has been lost, the chance of recovery depends on the drive family. With some older families the password can be bypassed; with most modern drives (particularly SED locked variants) it cannot. We verify the specific drive's status during the free diagnostics—a portion of users have WD Security active without being aware of it.

SMR recording in WD Red and other lines

The basic WD Red line uses SMR (Shingled Magnetic Recording) in current production as well—a technology in which write tracks partially overlap, increasing capacity but complicating random writes. The Red Plus and Red Pro variants are CMR. SMR drives may slow down under heavy load and cause problems during RAID rebuilds. From a data-recovery perspective, SMR is more complicated than classic CMR—even deleted data on an SMR drive may be inaccessible to standard software due to the controller's internal data management. The same behavior also applies to some WD Blue models that occasionally end up in NAS units they were not designed for. For a more detailed explanation of which WD lines use SMR and what it means for NAS users, see our article SMR—the hidden feature in some WD, Seagate, and Toshiba drives.

Slow Responding—firmware behavior in older and newer WD drives

A typical issue with a number of WD drives (both internal and external) is what is called Slow Responding—the drive is detected by the operating system and appears functional, but responds to requests with significant delays, file reads take disproportionately long, and transfer speeds fluctuate. The cause is usually a combination of several factors:

• Progressive degradation of the platter surface—bad or unstable sectors that the drive's firmware repeatedly attempts to read before returning the request or marking it as failed.
• Growing number of reallocated sectors—the firmware moves data from defective areas to reserve ones, which loads the drive's service area and slows down access.
• Service-data issues—inconsistencies in the translator, G-list, or P-list tables that the firmware must resolve in real time.

Slow Responding behavior typically precedes complete drive failure. If you encounter it on a WD drive, we recommend stopping work with the drive immediately—continued use generally worsens the condition and may lead to head crashing on the damaged area of the surface. Do not run standard OS utilities (chkdsk, fsck) on a drive in this state; they will repeatedly attempt to write to defective areas, deepening the problem. Data recovery from a drive in Slow Responding state is generally possible but requires professional tools for gradual and gentle reading.

Integrated USB connector in portable drives

In WD My Passport, Elements Portable, and some My Passport SSD variants, the USB connector (USB 3.0 Micro-B, USB-C, formerly mini-USB) is powered and signal-connected directly to the drive's PCB, without an integrated bridge chip in a standard slot. Mechanical breakage of the connector can result in damage to the drive's PCB itself. Such cases are also frequently associated with a drop, so the condition of the read heads and platters must always be assessed as well—users often focus only on the USB connector and fail to notice that the drive itself sustained additional damage internally.

For older and less complex drives, re-soldering the connector may sometimes be sufficient. For newer drives with SED architecture, the situation is more complex—it requires either work on the original PCB or transferring specific chips (ROM, controller) to a donor board, which must also be unlocked for communication with the specific drive. Amateur soldering attempts in home conditions risk damaging the ROM or MCU—if that happens, data on the drive may be permanently unrecoverable.

What to do when your WD drive fails

If your WD drive (internal, external My Book / My Passport, network My Cloud, or WD SSD) shows signs of failure, follow these principles—they determine the chances of successful data recovery:

1. Stop using the drive immediately. Do not power it on repeatedly, do not reconnect it, do not run any repair or backup. Every additional spin-up of a damaged drive can turn a recoverable situation into an unrecoverable one.
2. Do not attempt any repairs or recovery via unqualified service providers or software. Tools such as chkdsk, fsck, Recuva, EaseUS, or similar software can deepen the damage on a mechanically failed or surface-degraded drive—and in the worst case, overwrite the remaining data.
3. Do not open the drive or replace the electronics. On modern WD drives, simple PCB replacement from another unit does not work (SED locked architecture—see above). Opening the drive in regular conditions contaminates the platter surface with dust and, in most cases, results in permanent data loss.
4. Set the drive aside safely and contact us as soon as possible. Fill in the short form, call, or write—we will suggest the best path based on the type of drive and the failure described. Diagnostics and shipping to our lab are free of charge within the Czech Republic.

Important warning for encrypted WD My Book and My Passport drives: never run “Erase Drive” or “factory reset” functions from WD utilities. With some drive families, these operations generate a new encryption key, and the original data becomes permanently undecryptable.

For external drives (My Book, My Passport, Elements), the following specific principles also apply:

• If the USB connector is broken, do not try to repair the connector with a soldering iron at home—the risk of damaging the ROM or MCU during amateur intervention is high and may lead to permanent data loss (see the Integrated USB connector section for details).
• If the drive is protected by a WD Security password, have the password ready when submitting the job. For newer models, recovery without the password is generally not possible; for some older families the procedure can be discussed individually.
• After flooding or any other contact with liquid, do not power on or disassemble the drive, and deliver it to the laboratory as soon as possible. Hard drives are dust-tight and also resistant to water entering the internal enclosure, so in most cases liquid affects only the electronics (PCB) and possibly the external case—we handle these with standard procedures. Bags with desiccants and other amateur “drying” methods are not necessary and have no significant effect on the recovery process.

Indicative price of WD data recovery

The final price of WD data recovery depends on the type of drive, the nature of the failure, and the extent of the damage. For standard WD internal and external HDDs, the price is in the same range as for other brands; for drives with SED locked architecture, encrypted My Book / My Passport units, or damaged SMR lines, the work may be more demanding. We always determine the specific price after free diagnostics—you know in advance how much the recovery will cost, and only then do you decide whether to proceed.

Current prices for individual media types are listed in the price list, with more detailed information about the recovery process available in the individual pillar pages:

• Current data recovery price list—indicative ranges by failure type and medium.
• Hard drive (HDD) data recovery—comprehensive information for WD internal drives and classic external HDDs.
• NAS data recovery—for WD My Cloud and other network storage devices.

Diagnostics is always free of charge and non-binding. If data recovery is not technically possible, or if you decide not to confirm the price quote, you pay nothing.

Frequently asked questions about WD data recovery

My external WD drive is clicking, not spinning, or unresponsive after a drop. Can the data be recovered?

In most cases yes, but the outcome depends on how severe the mechanical damage inside the drive is. Clicking or ticking on a WD My Book, My Passport, or Elements most often indicates damaged read heads after impact—their replacement and data recovery is a standard laboratory procedure, but only if the drive is kept powered off and disconnected from then on. Every additional spin-up with damaged heads typically damages the platters where the data is stored, reducing the chances of successful recovery.

We always determine the specific condition through free diagnostics—we will tell you what happened to the drive, what path the recovery would take, and how much it would cost. Only then do you decide whether to proceed.

Is data recovery from a hardware-encrypted WD drive possible?

It depends on the type of drive, its age, and whether the user knows the password the drive was protected with. Encryption in WD external drives (My Book, My Passport) has gone through several generations over the past 15 years, and behavior differs between older and newer drives—with some older families it is easier to access encrypted data, while in newer drives (particularly 2.5" My Passport with a unique controller and ROM) encryption is part of the architecture with no possibility of bypass.

The practical rule that applies across generations:

• If you set your own password via WD Security, have it available when submitting the job. Without the password, in this situation we will most likely not be able to proceed.
• If you never set a password and the drive never asked for one, encryption typically does not prevent recovery—but we will confirm the specific status during diagnostics.
• The actual status of any given drive depends on a number of technical parameters (drive family, electronics generation, ROM type). Verifying it is a routine part of the free diagnostics.

My external WD drive is not detected by the computer. Is it the external electronics or a damaged drive?

Without physical diagnostics, this cannot be determined. The causes are typically threefold: external electronics failure (USB bridge in the enclosure)—relatively common after overvoltage or mechanical cable damage; damage to the drive's own PCB—often SED locked, requiring the specialized procedure described above; or mechanical or logical damage to the drive internally. Some of these manifest with the same symptoms but require entirely different approaches to resolve. In some cases, a PCB failure can also damage the internal electronics in the read-head assembly, which complicates matters further.

What you should definitely not do: repeatedly connect the drive, try different ports and cables hoping it will “kick in,” or open the enclosure and try to remove the drive. With the integrated USB connector on My Passport and Elements Portable, manipulation risks PCB damage. Diagnostics is free of charge, and distinguishing between failure types is its first step.

Do you recover data from older WD Caviar and HGST drives?

Yes. Older WD Caviar drives (Black, Blue, Green, Red prior to the 2011 rebrand) and HGST drives (Deskstar, Travelstar, Ultrastar prior to absorption into the WD Ultrastar brand in 2018) regularly arrive at our laboratory—typically from RAID arrays, NAS units, and desktops that have been in service for many years. Specific lines such as VelociRaptor 10,000 RPM appear less frequently. We keep thousands of donor drives and parts in stock, so for the vast majority of older WD and HGST models we have heads and PCBs immediately available; for rare variants we source parts from established suppliers as needed.

Specifics of older drives: WD Caviar lines typically do not use the SED locked architecture, so PCB replacement is more straightforward than for newer WD drives. For HGST drives, we work with tooling specific to that brand—part of which is shared with WD Ultrastar, while another part is exclusive to pre-rebrand HGST models.
