我买了一个二手 Agility 3 SSD。我想使用 hdparm 从我的 Linux 机器上删除数据。但不行。
以下是我遵循的步骤:
# hdparm --user-master u --security-set-pass 1 /dev/sdc
security_password="1"
/dev/sdc:
Issuing SECURITY_SET_PASS command, password="1", user=user, mode=high
# hdparm -I /dev/sdc
Security:
Master password revision code = 65534
supported
enabled
not locked
not frozen
not expired: security count
not supported: enhanced erase
Security level high
2min for SECURITY ERASE UNIT.

如果我没记错的话,这意味着驱动器已准备好擦除数据。但:
# hdparm --user-master u --security-erase 1 /dev/sdc
security_password="1"
/dev/sdc:
Issuing SECURITY_ERASE command, password="1", user=user
SECURITY_ERASE: Input/output error
此后,我看到的hdparm -I
只是以下内容:
# hdparm -I /dev/sdc
Security:
Master password revision code = 65534
supported
not enabled
not locked
not frozen
not expired: security count
not supported: enhanced erase
2min for SECURITY ERASE UNIT.

所以,我认为我没能擦除数据。对吗?如果是这样,您需要什么信息来帮助我擦除 SSD 中的数据?
