問題事象
Erasure of SSD and NVMe drives fails due to certain firmware based erasure commands failing or not being supported.
For example you can see one of the below mentioned failures being mentioned in the erasure report:
| Exception message例外メッセージ |
|---|
| ENHANCED SECURE ERASE command failedコマンドが失敗しました。 |
| SECURE ERASE command failedコマンドが失敗しました。 |
| FORMAT UNIT command failedコマンドが失敗しました。 |
| BLOCK ERASE EXT command failedコマンドが失敗しました。 |
| OVERWRITE EXT command failed |
| Cryptographic erasure has failed |
...
| コマンドが失敗しました。 |
| 暗号消去が失敗しました。 |
原因
Certain erasure standards (and erasure settings) incorporate firmware based erasure rounds which are mandatory in order to successfully complete the erasure. In some cases the drive may not support these required firmware commands (due to lack of the implementation on drive's firmware) or the drive might be in a locked state which prevents using these type of commands.
The commands used are dependent on the details of the target drive, selected erasure settings and erasure standard.

解決策
As a workaround, such drives can be erased using erasure settings which do not include firmware based erasure rounds during the process. Note that this type of erasure process will provide a clear level erasure results which protects against non-invasive data recovery methods.
