How run fsck?
 

I want to run fsck on my whole system (including FAT32 partitions and / folder. How can I get to single-user mode to run it? It is saying that running it on a mounted filesystem can really wreck things up. I don't wanna lose Linux again to my own stupidity like I did several times before. I am using Mandrake 9.

a) fsck doesn't check fat filesystems
b) for single user mode:
as root
# init s
then remount / read-only with:
# mount -o remount,ro /
