It's a drive in an eSATA external enclosure.
If you can figure a way to hook the data cable to a PC, you can run WD's own diagnostic software long test.
Either get the version from WD's web site that's an .iso you can burn to a cd-r as an image so that you can boot from it, or burn yourself a bootable copy of the free Ultimate Boot CD, which has the WD software and a bunch of other useful stuff.
Of course you need to make sure the power supply for the enclosure is still working properly, and you need to check the eSATA cable that connects the enclosure to the TiVo.
Lots of people have had the cable go bad, even though it's just been sitting there connecting the two and not moving.
