You never said what kind of motherboard and cpu you are using. There
are mb's with problems doing UDMA-100 and Via chips. This seems to be
especially true with AMD's. I have a KT7 and a Thunderbird that I
added a Promise so that it would do UDMA-100 without errors. I have a
Abit VP6 with 2-866's that does UDMA-100 in the individual drives mode
or in the raid configuration with out any problems.
