I don't know the filesize limit for DOS, but I thought it was less than
that. If you need to store large files, it's well worth your while to
find out what the size limits are for the filing systems available to
you (and use the one best suited).

I can't see why not. Hal cares about hardware being plugged and
unplugged. After that comes determining how to mount it.
If you're about to reformat the drive, and therefor don't have to keep
contents on the drive, you can test both of the above queries, yourself.

Unmount it (e.g. umount command, note that for some really stupid reason
someone decided to make the command umount not unmount--typical lazy
unix typists...), configure partitions if you need to (e.g. fdisk, or
other utilities), then format it (e.g. mkfs)
