SSDs are faster and mechanically more robust than traditional hard drives, but they have one major Achilles' heel: they generally fail without any warning. No unusual noise, no progressive slowdown — from one day to the next, the computer simply stops booting. In this case, data recovery is possible, but it follows very specific rules.
Why do SSDs fail?
Contrary to popular belief, flash memory chips do not last forever. The main causes of failure are:
- NAND cell wear: Each memory cell supports a limited number of write/erase cycles (between 3,000 and 100,000 depending on the technology). Past this threshold, the cell becomes faulty.
- Firmware failure: The internal microcode that drives the SSD can crash, rendering the drive completely inaccessible even though the memory chips are intact.
- Controller failure: The main chip that manages read/write operations can burn out, often following an electrical surge.
- Flash Translation Layer (FTL) corruption: The SSD uses a map to know where data is physically stored. If this FTL table is corrupted, the drive becomes unresponsive.
- Sudden power cut: An improper shutdown during a write phase can corrupt data in transit within the drive's cache.
The specific difficulty of SSD recovery
Recovering data from a failing SSD is technically much more complex than from a mechanical hard drive for three reasons:
- The TRIM function (and the new ray of hope): This command actively clears freed memory blocks to optimize performance. Long considered a death sentence for data, TRIM is no longer an absolute finality. Thanks to recent technological breakthroughs in laboratories, it is now possible, in specific cases, to bypass this command and recover files after a TRIM. It remains complex, but it is no longer impossible.
- Wear Leveling: To prevent wearing out the same cells prematurely, the controller scatters data non-linearly across the entire drive. Reconstructing a file therefore requires complex reconstruction algorithms.
- Native hardware encryption: Many modern SSDs (especially in recent laptops) automatically encrypt data. If the controller is damaged, the data on the chips becomes unreadable without the original hardware key.
Which cases are recoverable?
The success rate in the laboratory directly depends on the root cause of the failure:
- Firmware failure: Very good recovery rate (between 80% and 90%).
- Controller failure: Recovery possible via hardware emulation or by repairing the circuit power lines.
- Logical corruption (including after a recent TRIM): Excellent chances of recovery thanks to our new deep NAND flash chip analysis methods.
- Total wear of NAND cells: Partial recovery, depending on the number of sectors still readable.
Our approach at Belgium Data Recovery
To handle failed SSDs and apply the latest industry discoveries, our laboratory utilizes advanced equipment such as the professional PC-3000 SSD system coupled with our own research protocols.
These tools allow us to communicate directly with the SSD's processor in technological mode (Safe Mode). By freezing the execution of the original firmware, we prevent the drive from executing its background cleanup tasks (like TRIM or Garbage Collection). We can thus stabilize the faulty controller, manually reconstruct the virtual Flash Translation Layer (FTL), and extract raw data before it is permanently erased by the drive itself.
Our rates: Data recovery from a failed SSD starts at 360 € excl. VAT. Our policy remains unchanged: diagnostics are entirely free and without obligation (No Cure, No Pay).
One last piece of advice: If your SSD is approaching 5 years of use or S.M.A.R.T. reports indicate an increase in reallocated blocks, back up your data immediately. Do not wait for the crash, because SSDs never warn you.
