| Drive Eraser - 全バージョン | N/A |
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:
| 例外メッセージ |
|---|
| ENHANCED SECURE ERASE コマンドが失敗しました。 |
| SECURE ERASE コマンドが失敗しました。 |
| FORMAT UNIT コマンドが失敗しました。 |
| BLOCK ERASE EXT コマンドが失敗しました。 |
| OVERWRITE EXT 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.
To do this follow below steps:
- On Drive Eraser user interface navigate "Erasure Options" and click the gear-icon (or use keyboard combination CTRL+G) to open additional "Erasure Options" menu.
- Disable “Enforce Blancco SSD method on SSD” checkbox and click on “OK” to save the settings.
- Change the erasure standard using the "Erasure Standard" dropdown menu. Select a standard which does not include firmware based erasure rounds, such as "NIST 800-88 Clear".
- Run the erasure.
