 Someone's demonstrated you can hide in the firmware of
 hard drives.

Well, one would
assume this is also OS specific.  I would
guess it would be incredibly hard to make a "disk" virus
that would work on greatly differing OS's like Linux AND
Windows.  No telling what would happen if one of these disk
viruses got onto a hard drive on a Windows system and then
the drive was reformatted and loaded with Linux.
Most likely you'd have odd crashes or something.
