OK. Now I really am at a loss for words. I experienced my first FAILURE
message this morning when trying to fdisk my last newly formatted 160GB
drive. The second fdisk would start to write, my screen would fill with
WRITE_DMA WARNINGS and FAILURES. That was with another drive on the same
controller. I removed that drive, and everything works fine.
I just got another brand new 200GB drive within the last hour. Even it
on the same channel as anything else causes errors upon mount, and
FAILUREs as well. Then I cannot shut down properly because the errors
continue even to the shutdown sequence. Then on the next boot I get
messages about things not being properly dismounted. (First time
happening).
I don't know if it's hardware or FreeBSD anymore. I read this thread on
freebsd-stable earlier today, and then all of a sudden I start getting
all the failures that I never got before:
http://lists.freebsd.org/pipermail/freebsd-stable/2005-August/017636.html
So please, anybody...Is this a controller incompatibility with my other
hardware (drives) or a FreeBSD problem?
Up until now I was 98% certain it was hardware in some way, but now I'm
not sure. I have the opportunity to get an Asus board to test, but I'm
not going to shell out money for something if it isn't even a hardware
problem.
Thanks very much.

Well, it's a week later and I've been trying some things. I don't want
to get in to too much complicated detail, but I've now got the following
disk setup:
Primary Master - 200GB 7200RPM
Secondary Master - TDK VeloCD CD Burner
Secondary Slave - Sony DRU500A
RAID0 Master - 160GB 7200RPM
RAID0 Slave - 160GB 7200RPM
I don't have the two 80GB's or 60GB's in there now since I was just
testing with this setup. I thought keeping the OS drive on primary
master and the rest on RAID would do the trick, but it didn't.
Bottom line is, I'm still getting the same errors with several different
configurations of the drives. Now in the last couple of days I'm also
getting READ DMA errors when reading from one of the 160GB drives as
well. Before it was all just WRITE, but now some READs are thrown in
there as well.
I should note that I have never seen a "FAILURE" message, only the
"WARNING" messages. Also, if I downgrade the speed to UDMA100, it seems
to work just fine as it does in UDMA66 mode.
I'm wondering if anyone else has any ideas? Personally I'm out, and if
nobody else knows (including Maxtor, Giga-Byte, and my parts
distributor) then I'm going to have to see what I can do to get another
brand/model motherboard. I'm to the point where I think it's something
with their controller and how it handles Maxtor drives. Now that I
remember, I used to see similar results when running Windows on the
previous board before sending it in (same model). However Windows would
automatically take it down to 100 so I didn't see any errors.
Anyone think its something other than the board and it's controllers, or
is that a pretty good estimate?
Thanks in advance.

Okay well I tried another test. I left the 160GB on the primary IDE
channel, took out both optical drives, and put the 60GB on the
secondary IDE channel by itself.
I copied the data over again. No errors this time. I checksummed the
data, and everything is OK.

Without another known-working mainboard to test, you can't really be
sure, but it's a hardware problem of some sort, perhaps due to poor
cabling, perhaps a marginal or failing mainboard.
The cables are new, and the other drive on the same channel works in
UDMA133 with no errors.
The motherboard is new as well, fresh from the factory (unless it's
defective).
If you use BIOS or atacontrol to slow down to UDMA 33 speeds, does
everything work OK?
I tried slowing it down to UDMA66 speeds via atacontrol, and the
errors went away on the 80GB. I haven't tried the 60GB drive yet.
