Jon,

I did that, and it does not mention /dev/hda. However, I still get the 
different values for md5sum /dev/hda.

Right now, I am trying "knoppix nofstab nodma 3". I noticed that at boot up 
with the knoppix cd, there was a message about enabling dma for /dev/hda (or 
hd1 & hda2 - not sure). Anyway, that may have been a problem. 

I think Knoppix mounts local drives read only, but they do not show up using 
mount. I thought nofstab would prevent that, but obviously it did not. From 
http://www.knoppix.net/wiki/Cheat_Codes#Tips.26Tricks:

nofstab 
    By default Knoppix will look/scan the HDs to see if it contains 
partitions. If the HDs do have partitions, Knoppix will automatically build 
a '/etc/fstab' file and fill-in the appropriate partition entries and will 
also create the '/mnt/hdxx' mount points. The 'nofstab' cheat code prevents 
this look/scan and prevents the generation of the /etc/fstab and its mount 
points.

Anyway, without dma it takes a loooooooooooooong time to calculate a md5sum 
for a 30 GB disk!

I don't think there is anything wrong with my drive or RAM. It has been 
reliable and I have not had any problems. I leave the machine on for days, 
and it still keeps on going. The a/c in my office has not kicked in yet, so 
it has been toasty (above 80), and the machine has never hiccupted. It dual 
boots Windows/Linux, and even the Windows partition works reliably! ;-)

Thanks!

Mark
