I have a SSD disk with password protection, but the password lost long time ago... so I tried to earse the ATA security with "hdparm" command.
with "hdparm -I", the disk information looks interesting as below:
root@ubuntu:~# hdparm -I /dev/sda /dev/sda: ATA device, with non-removable media Model Number: TX21B10400GE8001 Serial Number: FG002VTA Firmware Revision: PRO6F515 Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0 Standards: ........................... Commands/features: Enabled Supported: * SMART feature set Security Mode feature set ........................... Security: Master password revision code = 65534 supported not enabled locked not frozen not expired: security count supported: enhanced erase 2min for SECURITY ERASE UNIT. 2min for ENHANCED SECURITY ERASE UNIT. Logical Unit WWN Device Identifier: 50011731001636dc NAA : 5 IEEE OUI : 001173 Unique ID : 1001636dc Checksum: correct
As you can see, the disk is in security locked state, and it doesn't support hdparm security mode feature.
When use security unlock command on this disk, the print out like below:
root@ubuntu:~# hdparm --user-master u --security-unlock 123456 /dev/sda security_password="123456" /dev/sda: Issuing SECURITY_UNLOCK command, password="123456", user=user SECURITY_UNLOCK: Input/output error
I'm wondering is there any other way to unlock this ssd disk and remove the password?
