How would a linux user reset the encryption key on a Seagate SED drive?
In Seagate nomenclature, changing the key is apparently by way of the "instant secure erase" feature. My BIOS has no such feature. Seagate offers no tools for this other than a proprietary windows-only API called "DriveTrust Security" (which is not available for download). There are a few commercial Windows tools that use the API, but the only option I've found for linux that might work is the IBM Tivoli Key Lifecycle Manager
(which is a pricey enterprise product, not fit for a home user who just wants to change the key on occasion).
I just discovered a similar thread
. Looks like a common and unsolved problem.
