How do you take Linux off of a hard drive?

[Michael Havens]

here is what knoppix says my computer looks like...
hda1 is windows
hda2 says that size = n/a and full = n/a so I don't care about that one
hda5 is Linux
sda1 is windows
When I first installed Linux I left a section to put /windows on (hda1).
The second one and the SCSI I put Linux on.
Now I have decided that I aint smart enuf for Linux so I put Windos back
onto my box and, with the aid of the Mandrake disks, made sda1 msdos format.
(I thought that was hda5 initially but discovered what it really was with
knoppix.
I have a Linux refrence book and in it is the instructions to create a file
system with "mkfs". I could attempt to make the filesystem on my own with
this information but I don't want to screw things up. Because of that I will
ask the all-knowing PLUG list what I should do.
mkfs -t msdos -c /dev/hda5
or
mkfs -t fat32 -c /dev/hda5
or what?
