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.
