Sure, not a problem. It's done all the time, and actually addressed quite frequently on the forums. I'll give you the quick and dirty, should it help. However, if you need more info a search will usually suffice. I will be more than happy to help if niether are helpful to you though, just post back
The quick and dirty:
mount -t vfat /dev/hdx /mnt/wherever
WHERE /dev/hdx is the fat32 partition (can be found by typing into a terminal as root:
fdisk -l (FDISK -L lowercase) and looking for the fat32 indicator)
AND /mnt/wherever is the empty mount point to mount it to.
If it all works out, and you want this partition mounted at each boot up, something like:
/dev/hdx /mnt/wherever vfat users,auto,umask=000,rw 0 0
As an entry in your /etc/fstab might work.
Cool
