Can you elaborate more on the Windows blocking of those ATA commands please.

I’m trying to send the SECURITY UNLOCK command to a locked drive using DeviceIoControl and IOCTL_ATA_PASS_THROUGH.
The return from IDENTIFY DRIVE says its locked but not frozen, and the password fail count hasn’t be hit, yet it just fails with aborted every time. Trying to find some info on why this could be.

No, it two different things… The data is not encrypted when you enable ATA security, the drive just prevents you from reading the data…. Whereas disk with encryption, actually encrypts the data on the platters.

Is the ATA Security Enabled HDD and the HDD with the Encryption enabled the same or Similiar?
