Hello,
Some problems. If anybody possibly might have some ideas regarding
what follows, I would greatly appreciate it. Otherwise, there are
several more diagnostic avenues hardware wise...
I just recently got a seagate barracuda drive and a adaptec 29160N
card. Since then I've been having reoccuring errors in files.
Sometimes only with specific files, though the choice seems random. I
am using Linux and the driver pointed to by doug from adaptec.
Basically, I'll do some form of writing to the drive and the kernel
SCSI driver generates this message (especially when moving specific
pieces of data, I even tried chopping files up w/ dd...):
scsi0: PCI error Interrupt at seqaddr = 0x8a
scsi0: Data Parity Error Detected during address or write data phase
seqaddr appears semirandom...
The error seems to corrupt files, which can be shown by unmounting the
partition and doing a simple cmp between the original and the copy.
Inaddition, the error seems to only occur when copying specific files
(notably several mp3s...). When creating (copying) files from two
different sources errors seem to start in the same place. I can also
make a copy, demonstrate that the copy failed, move the file and then
try again with the two bad copies being identical...
Originally, I thought this might be a cable/termination problem since
the drive was only negotiating at 40 MB/s instead of 160. However, I
replaced the cable and now am seeing 160 MB/s, but the errors persist.
In addition I had a similar problem with my SCSI burner earlier,
though I haven't tested it recently. I originally was using an
aha1522B with the burner.
Relevant stats...
I'm running Linux kernel 2.2.18 w/ aic7xxx compiled as a module and
scsi_mod/sd_mod(?) compiled into the kernel.
I checked that the PCI bus is running at 33 MHz w/ a frontside bus of
66 MHz. I have a pentium II 266 w/ 48 MB of RAM.

I'm wondering if this problem is specific to my motherboard. The docs
say that it is PCI 2.1 compliant and ATX 2.01. An old FX83-A.
thanks,
