How do I tell which kind of file system a hdd has in Knoppix

[HisHighness]

I've got viruses up the yin yang on my C drive for windows, so I'd like to use knoppix to clean it. I got f-prot working and all, but I'd like to have it clean it too. I've read it's unsafe to do this with NFTS but ok with FAT so I just want to know how to check which my C drive is in knoppix. I've tried right clicking and choosing properties but that doesn't work.

1) Mount the partition
If I remember correctly, this is simply a left-click on the partition's
icon; it should show a green "LED" afterwards.
If that doesn't work, open a console and type
<almost code>
mount -o ro -t xxx /dev/hdyz
</almost code>
Substitute "yz" with the appropriate value for disk and partition
(probably "a1") and "xxx" with "vfat" or "ntfs". A successful
operation should tell you the filesystem type. Oops, I assume too
much: should your disk be SCSI (or SATA) substitute an "s" for the "h".

2) Once the partition is mounted, type in a console
<code>
mount
</code>
All mounted partitions will be shown along with their types.

Thanks for the help.

It's actually even easier than that. You can see this information by an fdisk listing. Once you're in Knoppix, open the X terminal by clicking on Konsole (you're obviously this far anyway, but just for completeness).

In the terminal, type in the command

su

This switches you to superuser, which you need to run fdisk. Now enter the command

fdisk -l

You should get a listing that looks similar to this output that I pulled from Google (note that in this case the df command was also used):

# fdisk -l

Partition /dev/hda1 (probably C:\) is formatted with FAT, and partition /dev/hda2 is formatted with NTFS (possibly D:\ or E:\ in Windows).

You can also run

df -H

The -H switch provides a more readable output (MB or GB instead of 1K-blocks).

Maybe that will help anyone who does a forum search in the future.
