Chris,
Thanks for the info about your system…it provides insight. The
QULT540S arrived. I have it installed on a 50 pin header ribbon with
the 7120S. When ExpertPrep queried the drive it came back that the
drive had 58?? (I can't remember exact number) cylinders, 3 heads, 62
sectors per track…the information I got from Quantum indicates the
drive is 1048 cyls, 16 hds, 59 spt…so, after a bit of wrestling
around with ExpertPrep, I was able to force these numbers (the ones
from Quantum) and the drive formatted out to 515M. Does this sound
normal to you? Also, does it format to 515M because ExpertPrep
counts 1M = 1,048,543 bytes and Quantum rates the drive with 1M =
1,000,000 bytes?
Now, I am pretty certain that one of the drives *must* be terminated
for all to work properly, but since the combination didn't seem to
work correctly, I removed the terminating resistors from the Quantum
and, just for curiosity, checked the Maxtor (sure enough, it's
terminating resistors were gone, too). The drives now seem to work
fine together (except that I need to figure out how to make them
intelligent about which is supposed to be the boot drive). Is this
because the connector at the end of the ribbon header somehow
provides the bus termination, making the resistors not needed on the
drives?
I know I ask a lot of questions, but this forum is my best (best =
accurate + timely) source of information and I just want to make sure I
won't encounter irrecoverable problems when the drive is nearly full of
data due to incorrect setup due to my ignorance.
Thank you for your time and assist. ;^)
Have a Happy, Healthy and Safe New Year!
