Drive keeps disappearing???

[Boostage]

I have four 500 gig drives two are 32mb seagate barracudas. the other two are the 16mb version. one of the 32MB ones keeps disappearing. when copping large files. the OS doesn't freeze or anything. It just says something to the effect of source disk nor available. and then when I check My computer its completely gone. I thought it was some kind of built in overheating protection but its not

I have a 120mm fan blowing on all my drives. they never go past 35C according to Hardwaremonitor. and are always cool to the touch. I have tried changing the sata cable. that didn't help. this happens in both xp and vista. what could it be?

bad sata port or drive. Try connecting the drive to a different sata port. Did you try running diagnostic tools on it?

I switched ports then the mobo died.. not even kiddiing here. now I know why the machine kept randomly freezing also. the board was on its way out. I'll never buy a used board again. I'm getting a new Gigabyte board at Tigerdirect.

I have a 74 gig raptor that keeps doin this and no matter what diag tools i use it ALWAYS comes up with no errors. Also I have switched mobos 3 times. I may try it again here today.
