It could be the problem although I am not sure if there are any cabling differences between 66 and 100. Its quite possible the manufacturer just updated the sticker on the boxes to reflect that the drives "now work with ATA100" where as in fact they always did. Should be easy enough to verify if you run the drives without the trays. I buy trays locally from CCC (180 Columbia). They (Startech branded) are not high end by any stretch of the imagination, but they will work at UDMA100 and we use quite a few. BTW, I have been running the same MB with great results so far. Two 2000MPs. The primary drives are off a 3ware card, but there is one IDE drive that holds all the logging from a rather busy web server.
