Issuing SECURITY_UNLOCK command, password='123456', user=user When use the security unlock command on this disk, the results are as below: hdparm -user-master u -security-unlock 123456 /dev/sda

Logical Unit WWN Device Identifier: 50011731001636dcĪs you can see, the disk is in the security locked state, and it doesn't support hdparm security mode feature. Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0Ģmin for SECURITY ERASE UNIT. With 'hdparm -I', the disk information looks interesting as below: hdparm -I /dev/sda

so I tried to erase the ATA security with the hdparm command. I have an SSD disk with password protection, but the password was lost long time ago.
