I got a virus on my win xp a while back, and after a couple late nights trying to fix, I said screw it, its time to move to linux. So far I've been alright...

When I had windows xp on my machine, I created 2 partitions, the c:, and the m: (m for music)
Well it looked like the virus only attacked the c:...so I figured I could recover the data from the m drive when I got linux up and running

I used some partition manager.. and after switching around the partition type several times in an attempt to get it onto linux, It wouldn't work. On the partition manager I ran before, it said something about the partition not being valid

I downloaded QTParted, installed it, and when I look at the m partition (which I switched to ext3 btw) it says under type "unknown"
I don't know much about partitions, much less about linux, so if anyone knows a utility that will fix it automatically, that would be great...

or if I have to edit the partition file system, please help me step by step

Thank you for your time ^^

If you have not copied your data from m you should fix things. I hope you haven't formatted it when changing partition type? Run QTParted or any other similar tool and chage the partition type back to what it was. Only if you make it siccessfully (and the artition was not formatted in the mean time) you will be able to get your data back.

Whan it's done, you need to try to mount it? Was the partition NTFS or FAT32?

I made sure not to format the m:, just the c:. It was nfts, and I'm not too sure on how to mount a nfts on linux

That's common problem - RedHat and Fedora don't have NTFS support build in. You need to download NTFS RPMs from http://linux-ntfs.sourceforge.net/rpm/
