No.
/dev/hda = CD-Rom for me ("D:")
/dev/hdc = CD/DVD-Rom for me ("E:")
/dev/sda = Hard-drive
/dev/sdb = Hard-drive
/dev/sda1 = Windows partition ("C:")
/dev/sda2 = Linux partition (/)
/dev/sdb1 = Windows Partition ("S:")
Again, it will differ on your system.
Most of the directories come premade with your Slackware installation. I made dvdrom for myself, but cdrom was already there.
newby@impaler:~$ ls /mnt
cdrom/ external/ hd/ old-drive/ windows/
dvdrom/ floppy/ ipod/ thumbdrive/
/etc/fstab can link some of the drives to a specific mount point if you wish.
newby@impaler:~$ cat /etc/fstab | grep "cdrom"
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
You really don't want to mount a drive on boot. That's just retarded.
Mount them when you stick a CD in. Unmount (umount) them when you don't.
See, Joe, this is why you weren't a moderator of this board. This is really just a basic of *nix. As much as you may be relatively knowledged in *nix, you aren't totally knowledged enough to moderate issues revolving around it. You are all knowledge, hardly any experience.
