I think you are wrong too :-P The size of the IDE bus ( 16 bits ) didn't change since quitte a while, the only trick they found to increase data rate is to increase the bus frequecy as well. but something interessant is that on Yuval's system hda is on the same bus as a pio interface ( CDROM, Tape... ). And that _must be the reason_ of a slighty slower hard drive. In that way, this bus is maybe blocked at UDMA33 becaus e of the presence of an ATAPI interface. I have a single advice : *never mix HD ans ATAPI devices on a same bus* -- Nicolas -- [EMAIL PROTECTED] mailing list
