Using SCSI Hard Disk Drives

If you connect a SCSI hard disk drive to the Adaptec SCSI Card
■
39320D that was previously connected to a different SCSI card,
you must low-level format the drive before you can use it. Back
up the data on the drive before you format the drive. (See
SCSI Disk Utilities on page 3-15
SCSISelect format utility.)
!
Caution: A low-level format destroys all data on the drive.
Be sure to back up the data before performing a low-level
format.
Every SCSI hard disk drive must be physically low-level
■
formatted, partitioned, and logically formatted before it can be
used to store data. Most SCSI drives are preformatted at the
factory. If your SCSI hard disk drive has not been preformatted
at the factory, and if your computer is running under DOS, you
can format the disk with the DOS Fdisk and Format commands.
(See the DOS and Windows documentation for more
information.) To format SCSI hard disk drives running under
other operating systems, see the operating system
documentation.

Using Ultra320/160 Hard Disk Drives

■ We recommend that you connect your LVD (Ultra 320, Ultra160
and Ultra2) SCSI devices to SCSI Channel Aand your non-LVD
SCSI devices (if any) to SCSI Channel B. This allows the LVD
SCSI devices to run at their maximum performance levels of
320 MB/sec, 160 MB/sec. or 80 MB/sec. Or you can connect
LVD SCSI devices to both SCSI channels. If you combine LVD
and non-LVD SCSI devices on the same SCSI channel, the data
