780i dual SATA drives problem

[scenarioL113]

I have a 780i mobo and two seagate Barracuda Hard Drives 500 gig each.

I had originally had only one drive when I built the PC but the HD crashed and was RMA with a replacement sent under warranty.

I bought the 2nd drive while waiting for the warranty to happen. I setup the PC witht he new drive and all is fine.

I installed the replacement drive as a back-up for storage and all was fine. I noticed the mouse would get a little choppy from time to time but never gave it much thought.

Recently I noticed the backup HD was not being read by the MOBO. I opened the tower up and plugged and unplugged the wires and now it is recognized and all works.

I have the choppy mouse problem again and VISTA takes forever to shutdown.

If I disconnect the backup HD all these problems go away, NO choppy mouse and superfast shutdown.

I can obviously solve this by not using the 2nd drive but that is not really a solution.

I updated drivers and installed new SATA cables and switched out the power cables on my antec PS to be sure.


Is there anything else I can check. I moved my memory to different slots and different configurations and I reset the BIOS to default settings too.


HELP!......Please.

You can run Seagate's diagnostics, but since you already know that it causes issues, why not RMA that hard disk? It might have been returned for the same reasons and you're the lucky one who's got it.

I decided to wipe the drive clean. I ran DBAN and now everything seems to be running well.

I have now formatted the drive and have no issues as of yet.

Maybe I had some kind of virus on that drive, although IMHO I fell it was (possibly still) more hardware related. I guess I will put some backup data on it and see if it acts up again.

I always seem to have these weird problems.
