P4C800-E Drive light staying on.
 

I've got a P4C800E with 2 x IDE Hard disks on primary (IBM 80G and
Maxtor 80G) and a Pioneer DVD ROM 120s and Sony CD Burner on Secondary
IDE. A SCSI Drive connected to an Adaptec 2940 controller.

Occasionally the drive light will come on and stay solidly on with no
obvious disk activity going on - is this normal?

Thanks,

Rob.

Is this with Windows XP? If so I had that same problem with an IDE Iomega
Zip drive. Unfortunately my solution was to remove the Zip drive.
I would suspect your Adaptec 2940 controller but not sure.
