I missed the original post, but FWIW, I have had some trouble
with Adaptec 29320's. I have a Jetstor RAID-array which wont
operate beyond U160 when talking to Adaptec, but will run at
U320 when talking to an LSI-Logic adapter. This is identified
by the manufacturer as an Adaptec problem, to do with 16byte
CRDB's when using large logical-block-addresses.

I've also had problems with DLT2 tapedrives on these Adaptec adapters,
whereby unless I write records > 64K, records get dropped.
There is no problem with DLT1. I've not yet had the chance to
try the DLT2 drive on the LSI adapter.
