hi.

i'm trying to build this new box with a promise ata100
with 4 disk in a raid 0 setup.  at one point i was
able to get freebsd to newfs the disk but after other
problems and reconfigurations i can no longer seem to
do so.  the promise bios indicates the array is in
working order and on boot the kernel detects the array
as ar0 and each of the four subdisks. when i sysinsatll
and try to label and fdisk the array the kernel returns

ad4: UDMA ICRC error reading fsbn 0 (ad4 bn 0; cn 0 tn 0 sn 0) retrying
ad4: UDMA ICRC error reading fsbn 0 (ad4 bn 0; cn 0 tn 0 sn 0) falling back to PIO mode

in the mean time i'm going to try to futz with thing.
most recently the kernel and the card bios could not
stat the drive to get its identification but when i
moved the power cables from being close to the ide
cables it seemed to fix things.
