Thanks, you guys. I wondered if it might have something to do with the
software, because this is the second set of HD's I've had on there. Thanks
for setting me straight. I didn't know software RAID was so
nreliable. -Gary

I second that.
Using software RAID will likely result in a significantly slower
implementation than hardware RAID. In fact if not using Hardware, you're
probably better off file serving running off of one drive, then using a
nightly scheduled XCOPY to copy the user files to the second hard drive for
redundancy. Would probably be more reliable, and would also provide a
backup.
However, the hardware is pretty darn cheap. Want an IDE RAID 10 controller
for $62.34? Check out

So you have three drives total? Since you have one mirrored set C:
and a raid 5 set D: you must have them partitioned. I have to admitt
this is bad news. I would never recommend win2k based raid of any
form, Mirror or otherwise. I could understand 2 years ago when
hardware raid cost hundreds more because scsi drives and controllers
where so expensive, but now with built in IDE raid there is no reason
not to go with hardware.
Many of the problems I have experience with windows software raid
have been software related not bad hardware. Drives getting out of
sync due to software gliches is common place. I thought Win2k might
solve some of these issues, but not so. Even simple mirrors fail.
As far a diagnostics the windows basic windows tools may not cut it.
Chkdsk will look at file structure and surface problems, but buffer
and memory problems won't be detected everytime if they are
intermittent. Software like AMI Diag can run looping non-desturctive
tests that give more information.
