I have a weird problem with my PC, additional hard drives seem to "fall offline". What I mean is, they are no longer seen in "my computer". But the bois DOES see the drive. The drive is a western digital 250gb laptop drive, WD2500BEVE 2.5" eide drive. I am using and adapter to connect it to my ide ribbon cable. Could it be I need to set jumpers? my other four drives in the system are SATA drives and give me no issues. I also downloaded the diagnostic tools from WD and the drive checked out with ZERO errors! My mother board is an intel dg35ec and I am running Win XP. It actally has done this with Maxtor 500gb ide drives, I just assumed it was a bad drive, but I suspect it is something else. I seem to have MB drivers up to date.
