SCO UnixWare 7/OpenUNIX 8/OpenServer 6 FAQ : Media/Device Information, Filesystems, and Disks :
What is the device name of the diskette drive?
/dev/dsk/f03ht <--- These two are
/dev/fd0 <--- for filesystem use
/dev/rdsk/f03ht <--- These two are for
/dev/rfd0 <--- formatting, cpio, and tar
Diskettes are referenced by device files in
/dev/dsk/* <-- Block devices (diskettes with filesystems)
/dev/rdsk/* <-- Raw devices (diskettes made with tar or cpio)
/dev/dsk/f03ht <-- First 1.44 MB block diskette
/dev/dsk/f13ht <-- Second 1.44 MB block diskette
/dev/rdsk/f03ht <-- First 1.44 MB raw diskette
/dev/rdsk/f13ht <-- Second 1.44 MB raw diskette
/dev/dsk/f05ht <-- First 1.2 MB block diskette
/dev/rdsk/f05ht <-- First 1.2 MB raw diskette
/dev/rdsk/f15ht <-- Second 1.2 MB raw diskette
The specific device file to use depends on the density and size of the diskette and drive. The device file name consists of: f0 or f1 <-- The first or second drive respectively
3h <-- 3.5" high density (1.44 MB)
5h <-- 5.25" high density (1.2 MB)
t <-- The t specifies the entire disk
There are other diskette device identifiers like 3c, 3e, 3d, 5d, which can be found in the man 7 fd. In theory, /dev/[r]f03ct refers to 1.68 MB and 1.722 MB diskettes.

What about CDROM and tape devices like c0b0t0l0?
