Doesn't it require support from the BIOS, to prompt for the password on each boot? I have not seen anybody using this method, with Linux (on boot/system disk).
It does need bios support, but it doesn't work as you describe from what I understand.
The password is maintained by the bios. When the disk is powered on it initially refuses to accept read/write commands. The bios automatically sends the password and enables the drive.
Oh! :-o
How does the bios know the password? It has to be entered somewhere.
No user interaction required.
Typically a user would also have a separate bios password setup that has to be entered. But that is a separate password, so the user only enters the ata password once when the bios and the drive are paired together. Makes it very easy to forget.
Ah, I see.
But still I don't know how to enter, initially, the disk password. :-?
Carlos, Here's someone describing setting the ATA password via the bios of a Dell Latitude then using hdparm to clear it. http://thaeial.blogspot.com/2013/01/locking-and-unlocking-hdd-with-dell.html... I believe many/most laptop bios's offer a simple selection to enter the ATA password. When that is done they pair themselves to the drive. It is not an exotic feature.
