Floppy disks and some types of cartridge tapes
require preparation before you can create backups on them.
Before using floppy disks with the Backup Manager,
you might need to use the
command to format them.
You should format all new floppy disks and any disks formatted
under another operating system before using them on your SCO system.
Once you format disks, you can use them over again without reformatting.
However, disks formatted under some operating systems cannot be used
under other operating systems, even with reformatting.
Any data on the disk is lost when you format it.
Before using a cartridge tape with the Backup Manager,
you might need to prepare it.
Erase and retension the tape cartridge.
Format the tape.
You must format floppy-controller-based tapes before using them.
Before reformatting a used tape, you must erase it with a bulk tape eraser.
Do not format Irwin tape cartridges.
Use preformatted cartridges for best results.
Retension the tape periodically to fix slack tape problems.
Tape slack can cause unusually large numbers of tape errors.
Rewind to the beginning of the tape.
If you use tape cartridges that require formatting,
you should format the volumes before beginning the backup.
The exact number of volumes depends on the number
and size of files to be backed up.
For details on how to format your media, see
Chapter 7, ``Working with disks, tapes, and CD-ROMs'' in the Operating System User's Guide.
