Ah OK.  Though a cable fault does seem consistent with the evidence...
(I swear I read the FAQ before posting!)

In practice, does a BadCRC error EVER imply a crap/buggy chipset?

On the flip side, the cable isn't too long, isn't damaged, and was very
definitely seated properly (I did it personally and took some care over
that).  On the third hand, I don't know where it came from, and somebody
had spilled coffee on it in a previous life :-) (not the connectors!).

To approach the question from a different angle completely: DARE I use
the VIA 686A in UDMA-33/66[/100 if capable?] mode, or is it not really
up to the job?  I've seen so many posts on a search for "linux via ide
corruption" that I'm uneasy about repeating the experiments on what is a
production box...

thanks,
Neil
