SSD not detected, corrupted USB drive or unreadable SD card? Our technicians work at the electronic level to extract your data directly from NAND chips.
SOS-DISQUE has an office in Paris. Technical work is carried out by a specialist partner laboratory in Romania, using our shipping service. We do not offer in-person drop-off or cleanroom visits.
SSDs have no mechanical parts. Their faults and recovery methods are fundamentally different.
Unlike a mechanical hard drive, an SSD stores data on NAND Flash memory chips. A controller manages writing, reading and cell wear through complex firmware.
When an SSD fails, the problem is generally:
On an HDD, data is written sequentially on platters. On an SSD, it is fragmented and encrypted by the controller and spread across several chips.
Recovering the data often requires:
This is why consumer recovery software is completely ineffective on an SSD with a hardware fault.
Samsung, Crucial, WD, Kingston, Intel and others. All formats: 2.5-inch, M.2, mSATA, PCIe. Controller faults, firmware faults and NAND wear.
SanDisk, Kingston, Verbatim and others. Drive not recognised, formatting requested or missing data. Direct extraction from NAND chips.
Lost photos and videos? A corrupted or unreadable card, or one reporting errors. Recovery of photos, videos and documents.
Samsung T5/T7, WD My Passport SSD, SanDisk Extreme and others. The same NAND technology and recovery methods.
The BIOS or operating system no longer sees the SSD. This is often related to the controller or firmware. The SSD may be in brick mode.
SSD not detected: complete guideThe SSD enters a protective mode when its NAND cells reach their wear limit. Data can be read but no longer changed.
Windows asks you to format the drive? The partition table is corrupted, but the underlying data is intact. Do not format it.
Unlike an HDD, an SSD uses the TRIM command, which automatically erases data blocks marked as deleted. This means:
If your SSD has a problem, switch it off immediately and contact us.
Yes, in most cases. Recovery differs from an HDD: specialist tools are needed to access the NAND chips and reconstruct the data. It is more complex, but our equipment makes it possible.
Do not format it. This message means the partition table is corrupted, but your data is probably intact. Describe the symptoms online for an initial assessment before shipping anything.
Probably not. SD cards use Flash memory like SSDs. Our tools can extract data directly from the chips, even if the camera or computer no longer recognises the card.
Yes. The price depends on the complexity of the work, rather than just the device type. The initial online assessment is within one hour; the recovery balance is payable only if recovery succeeds. View our prices
Initial online assessment within one hour. New cases: O, A, B and B+ have €30 initial postage and no investigation fee; C and C+ have €130 initial investigation. The initial amount is deducted once from the recovery price on success and retained on failure; no recovery balance is due on failure.
