I got Win32.Virut.56 virus, which is a very nasty stuff. I reinstalled my Win7, but it reappeared somehow. After hours of headache, I was able to remove it by booting into a live Ubuntu and running CureIT using Wine.

I then started reinstalling Windows 7. After the "expanding files" stage it rebooted, however from that point on, my 160 GB Western Digital SATAII hard drive was not recognized. The bios just freezes at "SATAII 1: Detecting...".

My other 1.5 TB Seagate SATAII hard drive works correctly.

I tried switching cables; that didn't help. I googled this issue, but what came up were usually firmware problems. I can't update the firmware or do anything at all, because if I plug it in, it won't start.

My motherboard is an ASRock 4Core1333-Viiv, if that helps.

I'm now stuck on a live Ubuntu. I can't install Win7 on the 1.5 TB drive, because it's full of data I need.

What do you think I could try to make the hdd work again?

As for the moment, I don't have another computer to try if that one recognizes the hdd.
