hmmm - I wonder if that is a recent change? I'm still on 2.4.20 and this is my hdparm -v -i UDMA modes: udma0 udma1 udma2 udma3 *udma4 UDMA modes: udma0 udma1 udma2 udma3 *udma4 udma5 First is my 13 gig primary and second is my 30 gig secondary. I'll have to triple check the cable when I get home to make sure that's not the bottle neck. I know the board will do ata/100 since I had that drive on the other channel before I bought a dvd drive and it was doing it there. -- [EMAIL PROTECTED] mailing list
