I'm considering buying Crucial M500 SSD drive with SED (self-encrypting drive; ATA password, TCG Opal 2.0, eDrive compliant). I'd like to use its SED functionality, but even after reading a bunch of articles, I'm still puzzled about the exact requirements.
I have an older (2008) motherboard without the ATA password, UEFI and TPM functionality. This is, of course, non-compliant with eDrive specifications, so I'm not able to use Bitlocker. Same goes with the ATA password, since my mobo doesn't have such a feature (I don't want to use ATASX, as it lacks AHCI mode).
I set my sights on the SSD's Opal functionality then. I came across two software products (Wave Embassy and WinMagic) that are able to provide pre-boot authentication, but I don't understand what are their exact requirements. Do they make use of SED via Opal even without ATA password/UEFI/TPM enabled motherboard?
The computer will be running Windows 8.
Note: My goal is to enable basic encryption to protect the computer from common thieves. It's not going to be analyzed by NSA or people with mad skills in the field. With that said, I'm OK with using proprietary software.
