Is my Asus P5QL Pro killing hard drives

[Redeyeburn]

I had 3 hard drives crash a few days ago, so I disconnected one that was ticking, left the other 2 connected, and after multiple reboots they started working again, then they wouldn't, then they would, and so on, so I disconnected the 2nd hdd, and only had the op' system drive running, then it started ticking.
So I bought 2 new Western Digital Caviar Black 640gb's, copied my data to one, then disconnected it and installed my opp' system on the other, then I connected them both, and now not even the bios see's the 2 new hdd's.
Did I kill the 1st new drive running it at the same time as one of the other bad hdd's then kill the 2nd new hdd when I ran it with the other new hdd that had been connected at the same time as one of the old drives?
ANd I can't figure out what's causing all this.
I'm at a loss here?:shocked:😕

Are you getting any disk controller errors or drive errors in your event log? Have you ran dskchk or disk repair on them? It does sound strange for three to go bad all at the same time. Never heard a bad one casuing a good one to go bad. Have you tried updating your disk controller drivers?

I can't get in the opp' system to see anything in the event log, the bios won't even recognize the drives now. I did run dskchk on the old op' system drive and came up with 4 errors, and thats the one that started clicking and died last night, I can't do anything at all with the 2 new drives.

Turns out it was the psu, put an old one in there and it all works again. I did have to write zero tracks across one entire hard drive, but it's good to go now.

I was just about to propose changing your PSU. I was late to the party again! Doh!
