OK. Here's the output of hdparm -iv for the drives:
6.4Gb PRIMARY - USES UDMA successfully:

10.8Gb SECONDARY WON'T USE UDMA UNDER LINUX (fails with resets and lots of errors):

The SMART STATUS of both devices indicates that they are functioning "perfectly" (or
at least aren't going to fail anytime "soon").
Thanx guys,
BIG JM.
