Also, adding to the prefectly fine answer by Cybergod1983
there is a folder in which all your drives should be at.
just type cd /mnt
and in there you should see cdrom, floppy, etc... depending on how many drives you have. For example I have
and because I have two hardrives I also made two other folders to access my windows hardrive
and so it makes more sense to the person who is new to linux, you can just type
mount /mnt/floppy for your floppy drive and
mount /mnt/cdrom for your cdrom
to pull out the cd or the floppy now...remember to do exactly the same thing, only the command is umount
have fun!, it's Linux!
