============================================
Hello Andrew:

Thanks for the reply. BTW my email was returned so had to post.

I bought the card used and it came with disks, not a CD. Also my 2 HDs are
internal and the CD is external. My procedure is always to copy my current
system to the other HD and use it to start up from.

I reformatted (HDT 1.3) my HD and installed the 7.1.2 system that came with
the card. Then restarted and installed 7.5 CD, then restarted and installed
7.5.3 CD. I enabled the card from the control panel but not the MMM in
memory, first, then restarted with only system extensions. (Both my drives
have HDT 1.3 drivers.) When I reformatted the drive with Hard Disk Toolkit
it installed the updated driver. Right? So I don't see how that could be
the problem.

 And since the MMM was off, I was not running any PPC programs, and the
drivers were current, how could the above be true?

Thanks again.
