Its system drive had failed, and because it ran Windows Embedded Standard 7, which could no longer boot, the machine came to a complete halt. The control application could not start, and production stopped.

Yet where their speed is an advantage, the TRIM and Garbage Collection functions can be surprisingly slower — fortunately for a desperate user who has just lost data. Until recently, it was believed that once an SSD was deleted or formatted, the chances of data recovery were practically zero. TRIM and Garbage Collection were thought to immediately “clean” all cells that contained data prior to deletion. However, as shown by findings presented at this year’s **Techweek 2025**, the reality is far more interesting.

They serve as central storage, backup and multimedia libraries. Although they offer a degree of data safety thanks to RAID arrays, situations can arise where all data suddenly becomes inaccessible. This is exactly what happened to the user of this Netgear NAS.

It shows whether a drive can be safely read and helps determine the right recovery method to minimize the risk of permanent data loss and maximize the chances of successful disk recovery.

The problem may lie in the PCB itself, it can be caused by user-induced mechanical damage, or it may involve a combination of issues where the PCB isn't the main culprit, but its technological intricacies still need to be navigated. This particular drive required PCB modifications; fortunately, the data platters and read/write heads were intact.

After Years in a Drawer, It Refused to Turn On](https://www.exalab.cz/images/blog/EN2501121-w1200-fw.jpg) ## [ Data Recovery from an Older Mobile Phone. After Years in a Drawer, It Refused to Turn On ](https://www.exalab.cz/en/blog/from-practice/labnotes/data-recovery-from-an-older-mobile-phone-after-years-in-a-drawer-it-refused-to-turn-on) When switching to a new mobile phone, some users transfer and back up their data immediately. Others postpone this step for various reasons, leaving the old device stored away until the "right" time arrives. This was exactly the scenario with this Lenovo phone.

One of the most critical complications with SSDs is the failure of their controller, which ensures communication between the memory chips and the computer (or other device). If the controller fails, recovering data from such an SSD can be very challenging – and with SandForce controllers, often impossible.

However, with external drives, it is impossible to completely rule out the possibility that an accidental drop or impact may have contributed to the issue. Fortunately, there was no evidence of extensive mechanical damage to the read heads or data platters, and the disk could be partially initialized. However, the data was only partially accessible, so it was essential to choose the correct procedure from the very beginning.
