I'm trying to salvage some information from my aunts hard drive using knoppix (she got a pretty bad virus), but I'm having trouble mounting her hard drive.

I use
Code:
mount  -t ntfs /dev/hda1 /media/hda1
and get the error

Code:
Failed to startup volume: Invalid argument
Couldn't mount device '/dev/hda1' : Invalid argument
Mount failed.
I obviously am doing something wrong, but I'm uncertain what. Any ideas?

Thanks,
Arthan Khwelnul
