Dead or undetected SSD: what to do?

Symptoms of a failing SSD

An SSD rarely fails gradually like a mechanical hard drive: there is no noise and no warning slowdown. The most common signs are:

• Not detected: the SSD shows up neither in the BIOS/UEFI nor in disk management.
• Nonsense capacity: it is recognised, but as 0 bytes, 2 MB or a generic model name (often the controller's name).
• Read-only: data can still be read but every write fails. Many SSDs deliberately switch to this mode when their cells are worn out.
• Errors and crashes: blue screens, corrupted files, random boots, SMART attributes in warning.

Checks before concluding it has failed

Many "dead" SSDs actually suffer from a connection or configuration problem. In order:

1. Try another port and another cable (SATA data and power for a 2.5" drive). For an M.2 drive, try another slot or another PC.
2. Use a USB adapter (SATA or NVMe enclosure) to check whether another computer sees the SSD.
3. Check the BIOS/UEFI: SATA mode (AHCI), an M.2 slot disabled because it shares lanes with a SATA port, a BIOS update for recent SSDs.
4. Check the SMART status with the manufacturer's tool or a utility such as CrystalDiskInfo (Windows) or smartctl (Linux, macOS).
5. Look for a firmware update: some models had bugs that made them invisible or locked them up, fixed by the manufacturer.

Recovering your data: what is possible

Data recovery is harder on an SSD than on a hard drive. The TRIM command quickly wipes deleted blocks, and many SSDs encrypt data at controller level: when the controller is dead, the chips alone yield nothing usable without it.

If the data is valuable and no backup exists, contact a specialist lab before doing anything else (reformatting, resetting, firmware update). Ask for a diagnosis and a quote: the cost depends heavily on the model and the fault.

Under warranty? Start with the manufacturer

Most SSDs carry a 3 to 5-year warranty, often with a written-data limit (TBW). If yours is still covered, a return request (RMA) to the manufacturer or seller remains the best option: you get a replacement or a refund.

Note that the returned SSD is generally not given back. Wipe it if you can, or check the manufacturer's data policy.

Out of warranty: don't throw it away, sell it

A dead SSD is still waste electrical and electronic equipment (WEEE): it must not go in household waste. You can take it to a recycling centre or an in-store collection point, but you can also get money for it.

An SSD failure almost always comes from the controller, the firmware or the power circuitry, very rarely from all the memory chips. Those NAND chips are reused as components. That is why Recychips buys SSDs at the same price whether they work or not, per terabyte based on the label capacity: see our prices for NVMe and M.2 SSDs, 2.5" SATA SSDs and enterprise SSDs.

SSDs are dismantled in our workshop, no data is read and nothing is resold as is. Still, read our guide on wiping an SSD before parting with it.

In short

1. Check cables, ports, BIOS, SMART and firmware.
2. Back up immediately if the SSD can still be read.
3. Valuable data with no backup: specialist lab, without trying anything first.
4. Under warranty: RMA request to the manufacturer.
5. Out of warranty: sell it for its chips rather than binning it. Value your batch online.
