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.

Resolution

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.
