Posted May 19, 201410 yr I'm using a Thinkpad T440p with Samsung 840 Pro SSD. I set an ATA password that is requested every time the drive turns off. So when I boot any OS from cold it asks for the password, but if I reboot Windows it doesn't, because the drive doesn't get turned off and therefore does not forget the password. The same behavior happens when I reboot using Ctrl+Alt+Del from DOS or early in the Linux boot process. Unfortunately when I reboot Linux after completely starting up (so that a reboot actually isn't instant, but Linux gets time to shut down properly), the hard drive seems to forget the password. The computer just turns off at the point where it would say that the password is still there. Presumably at some point in the reboot process Linux turns off the hard drive. Does anyone know when that happens? It would be great to be able to quickly switch between Windows and Linux. Sorry if this is the wrong forum, but it seemed like the only one it might fit in.
