I'm upgrading to an Intel D845PESV MB with WinXPPro.
It's in a Lian Li case with two Lian Li RH-321 hard drive mobile racks.
The top drawer, primary drive, C: is a Maxtor D740X-6L 40Gig jumpered as master
It's on the end connector of cable from Primary IDE channel
The bottom drawer, backup drive, D:, is a WD400 IDE 40Gig jumpered as a slave
It's on the middle connector of cable from Primary IDE channel

The HD drawers have drive activity lights. Whenever the computer is on,
both HD activity lights flash in unison all the time, from bootup until
shutdown. I would expect only the C: light would be flashing until the D:
drive was asked to do something.
I changed the jumpers on both drives to "Cable select" and it acts just the
same.

I have used this same setup on W98 machines for a long time and never saw
this. The D: drive always used to "sleep" until I Ghosted C: to the D: for
backup purposes. Anybody know why this is happening? Is this a false
indication? Are both drives being written to identically? Is there a way to
check to see if drives are identical? Should they be on different IDE
controllers? Is this an XP or a hardware problem? Thanks for any
input.  Bob Lendrim
