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

As you can see, the disk is in the security locked state, and it doesn't support hdparm
security mode feature.
When use the security unlock command on this disk, the results are as 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 if there is any other way to unlock this SSD disk and remove the password?

I was able to get this to work on my Western Digital WD20EURS. After piecing together tips from all over Google, I was able to get a master password, research the commands of
hdparm
, and use your example in your original question to resolve my issue. Maybe this will help you too.First off, I found a list of master passwords for various brands of drives.
Here are two locations, (replaced with Web Archive versions to avoid link rot)
My method:
yum install hdparm
)hdparm -I /dev/sda
to check if drive was "locked" ( -I is capital i )hdparm --user-master m --security-unlock PASS /dev/sda
hdparm -I /dev/sda
again ( -I is capital i ). This time the drive showed "not locked" (at which I hesitantly rejoiced)hdparm --user-master m --security-disable PASS /dev/sda
