hi all,

I have two drive-related problems that may or may not be related. First
off, let me give you some specs on my machine:

ABIT VP6 mainboard 2x933MHz processors
HPT370 onboard UDMA/100 controller
4x256MB PC133 SDRAM
1 IBM 75Gig HD
1 Western Digital 60Gig HD
16X Pioneer DVD drive
10X/8X/32X HP 9300 CD-RW drive

the drives recognize fine in the bios and everything, I have them both
hooked up to the Primary controller on the board. When I boot FreeBSD I
get the following messages:

ad4: 73308MB <IBM-DTLA-307075> [148945/16/63] at ata2-master UDMA100
ad5: 57241MB <WDC WD600AB-00BVA0> [116301/16/63] at ata2-slave UDMA100

acd1: CD-RW <Hewlett-Packard CD-Writer Plus 9300> at ata0-slave using
PIO4

I am not sure if this is a controller problem - I've swapped out the
CD-RW drive for a Sony model and I get the same result. Afterwards, when
I start using the box [logging in, etc] I get the following:
ad4s1a: UDMA ICRC error reading fsbn 68463183 of 34231560-34231687

so on and so forth..

ad4s1a: UDMA ICRC error reading fsbn 282735839 of 141367888-141368143
(ad4s1 bn 282735839; cn 30950 tn 120 sn 29) falling back to PIO mode

and the drive falls into PIO mode. I've tried changing to a higher
quality / longer cable.. same result. I haven't found any hard evidence
of known issues like this while doing web research, but I've noticed
people with similar problems and different controller cards. Any insight
that could be provided would be greatly appreciated. More info:

Thanks in advance,
