That is a valid answer i can relate to.
Motivated, I read all i could find about full disk encryption (starting from here: https://en.wikipedia.org/wiki/Hardware-based_full_disk_encryption).
Unfortunately, it *seems* to me, you need a self-encrypting disk (like your samsung), and with the help of the Motherboard security setting, you can set the required password.
I could not find many chipsets (one from intel being the exception, which longs has been abandoned) where you would need just the Motherboard to enable a full disk encryption.
As you might guess, i'm not exactly an expert on this, so forgive me for retreating silently without a useful answer.
