File corruption

Hello,

I am a user of an IT8212 RAID controller (a cupple hundred kb worth of
on-board cache) with 2 identical Western Digital 40GB drives (8MB of
on-board cache).

I've configured this hardware to a 80GB RAID0 stripped array, 1 kb strip
width (to maximize preformance). I've formatted it into 3 partitions of
approximate equal size (to keep my files better organized). I use
Windows 98SE, which is installed on a small fixed independend 6 GB drive.

However ever since I began using the RAID array I get constant data
corruption (I've switched all the hardware once, but not the contens of
any of the drives, and the problem remains). After every reboot, the EXE
and DLL programs get errors, (text, documents, archives, source code,
etc are unharmed). After I overwrite the EXE or DLL files with an
identical copy from the same drive (or usualy one of the system ones,
since there they are safer), they work fine until the next reboot.

I use a good anti-virus so this couldn't be the source, anyway if it
were, the fixed system drive would get errors as well, but it's working
fine.

What is causing the corruption and how do I prevent it?

Thanks in advance.

Can you capture some samples of corruption, by comparing
a corrupt file to a non-corrupt backup?

If it is single-bits, memory somewhere is likely to blame.
If it is bytes or bursts of bytes, it is more difficult.

Could be a bug in the chipset or a bug in the software
drivers. Or bad cables (although the O/S can usually
detect that).

I have a Tyan motherboard which will consistently
corrupt data under Win2000 server if I try to use those
particular built-in RAID ports. Only workaround was to
not use those ports and add in a RAID card of my own.
Took me a week of building the system multiple times
before I tracked down why things were going wonky.
