Sometimes when i start my computer my hdd doesnt show up in the bios(it is the boot drive). I have to turn off my computer, open up my case and unplug the power cord from the hdd and once i do that the bios will recognize it again. This seems far from normal behavior. I have a 3month(ish) old Antec True430 and the rails are 11.74/12;4.91/5;3.23/3.3 in AsusProbe so i dont think the PSU has anything to do with it. The HDD is a WD 800jb 8mb cache 80gig bought in sept 02. it has a 3 year warranty which is good news if it ends up being something to do with the hdd. I am using a hard drive cooler so it's never too hot. I have no clue as to the cause of this. Anyone? thanks
