Drive access problem

Alright, I can't access my D: drive.

This all started today when I turned on my computer and the hard drive light continued to flash even though all loading was done. When I tried to got to My Computer, it went unresponsive at first, and the D: drive had some how mysteriously renamed itself to Local Disk when it had previously been named something else.

I ran Spy Sweeper and it found something called Trojan_backdoor_zubox_1.

I imeadiately removed the Trojan with Spy Sweeper. However, my computer is running slower than usual, My Computer is a bitch to access and when I try to access D: (after fighting with My Computer to work) it says something like "Cannot access D:. There is an I/O device failure". However, the system says that the hard drive is healthy and functioning properly. I can access E: which is on the same hard drive as D:.

Can anyone help?

(And yes, I'm using Windows XP)

I mean, ATI cards, not bad, I don't think.  But a card has to have decent drivers, or it ends up just being ass.  ATI's drivers have gotten progressively worse over the years.

But anyway, back to the disk error, I would try booting into like, a knoppix live CD, and trying testdisk on the thing.  If the partition is damaged, it may be able to find the partition, and repair it.
