I have a backup 80gb Seagate Baracuda IDE installed on my Gigabyte GA-P35-DS3L MB and it has disappeared three times in the past day. Reboots or cold-starts wont solve the problem, I have 'fixed' the problem by opening up my case and reattaching the IDE cable to the HD and the MB. I can't figure out what the cause is, the HD has simply disappears after the computer has been on for a couple minutes to hours. The BIOS doesnt recognize it, then I reattach the cables and walla its back. CHKDSK reports no errors. Any ideas, is this HD in imminent crash?
