Disk question

[Tim Darby <t+dfbsd@xxxxxxxxxxxx>]

I have a machine that was running Windows XP until I recently
installed 2.2.2 on it.  This was mainly for the purpose of trying out
Hammer.  It contains a 40GB drive, which I made the boot drive and
installed with Hammer.  The other 2 drives are a 300GB Samsung IDE and
a 200GB Western Digital IDE, both connected to a SiI 0680 controller.
I've succcessfully installed Hammer on the WD drive, but the Samsung
fails as follows:

# newfs_hammer -L BACKUP /dev/ad6s1a
Volume 0 DEVICE /dev/ad6s1a     size 279.46GB
initialize freemap volume 0
ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=2245359
ad6: TIMEOUT - READ_DMA retrying (0 retries left) LBA=2245359
ad6: WARNING - READ_DMA status=51<READY,DSC,ERROR>
error=84<ICRC,ABORTED> LBA=2245359
newfs_hammer: get_buffer: /dev/ad6s1a:2000000000814000 Read failed at
offset 1149583360: Input/output error

I ran a Samsung diagnostic on it and it found a DMA command timeout
problem (service code AJ27), so it appears that the drive really does
have a problem.  Just for kicks though, I tried installing UFS on this
drive and it gave me no complaints and seems to actually work.  Also,
Windows XP seemed to be working fine with this drive.  Does that make
any sense?
