Formatting the drive
Warning. Formatting a drive erases all user data. Be
sure that you understand this principle before
formatting any hard disc drive.
It is not necessary to format a drive which has
previously been used to store data, unless
your intention is to erase all user data.
1. Turn on DC power.
2. Boot the system from a system floppy disc or from a
previously installed hard disc drive if there is one.
3. Format the disc drive. The Barracuda 1 and 2 disc
drives are designed to operate with a variety of
operating systems; therefore, please refer to your
system or SCSI controller manuals for information
about formatting and setting up the drives.
