I just upgraded a machine with two IDE disks (one master on each channel, with CMD640 stuff). One of the drives is at least 7 years old. wdc1: unit 0 (wd2): <WDC AC2420H> wd2: 405MB (830760 sectors), 989 cyls, 15 heads, 56 S/T, 512 B/S With ata driver, an attempt to mount the partition on the drive would result in a hang (not even console-switching would work) right after the partition parameters were printed by the kernel (booted with -v). Both of the drives were being accessed in pio mode automaticly, judging by the hw.ata... (pio,---,pio,---,). The first disk, which is newer worked fine. With wd driver the second drive "just works"... This was with 4.0-RELEASE. I have since upgraded to the 3 days old -stable, but have not tried ata again. -mi To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
