Full disk encryption from disk drive manufacturers?

[spencerforhire <spencerforhire () gmail com>]

Does anyone know a source for Seagate Momentus 5400 FDE.2 hard drives
which support full disk encryption?  Are they produced anymore?

Also, are there any other drives available to OEMs or retail which
support full disk encryption?  I heard Toshiba may be releasing a
similar product?

I'm aware of the software products available to provide disk and
volume encryption, but I'm curious about the drives which support
these features in their firmware.

Thanks!
