Cause
This issue is caused by non-standard firmware available on these SSDs. Affected drives are not capable of executing "Secure Erase" or "Enhanced Secure Erase" firmware based commands properly, which leads to a scenario where the disk is no longer being detected after these command have been executed.
...
In order to prevent this issue from occurring it is recommended to use erasure settings which won't utilize Secure Erase/Enhanced Secure Erase as part of the erasure. This can be achieved by using for example NIST 800-88 Purge.
| Info |
|---|
Note that if the automatic fallback from NIST 800-88 Purge to NIST Clear 800-88 is used in the image, the firmware based command "Secure Erase" is performed and issue will appear. This is caused by the used commands of NIST Clear 800-88. In this cases it is suggested to use a non firmware based standard like Aperiodic Random Overwrite. |
