Writing a file to the drive the other day it coredumped.
So I pulled the drive and booted to an old WIn98 foppy and partitioned and
formatted the drive just to start from scratch, no problems indicated in
that process.
Then I CVSUPed to RELENG_6_1. No problems upgrading at all.
I reinstalled the drive with a different cable and put it on the secondary
slave position, and fdisk and labeled per sysinstall, full use, no MBR
changes.
I tried different bios settings like auto recognition, user defined, with
LBA, Normal and Large Modes. No change.

fsck /dev/ad3s1d looks good this time but same dmesg errors exists on boot.
This an older Maxtor 72004 AP 2Gig

Could be time for trashcan to take ownership.
Any more ideas?
