I've ordered a Samsung SSD (850 PRO SATA) that supports TCG Opal 2.0.
At first I was planning on setting an HDD password (aka ATA password) via BIOS. But motherboard manufacturers don't seem to specify whether this functionality is supported by the motherboards. My understanding is that with TCG Opal we can skip the BIOS entirely and set the disk password using a tool such as sedutil. The disk itself then has a shadow operating system that asks for the password during boot, independently of the whatever operating system is in use (in my case linux) and of the BIOS.
I have two questions about drive portability and hibernation support.
- Can I take an encrypted disk, with the password set (TCG Opal), and move it to a different computer? Since the password is stored inside the disk and handled by this shadow OS I'm assuming this will work, but I couldn't find confirmation anywhere.
- Will hibernation work as usual and is the password for the disk asked after booting the computer from hibernation?
