Chapter 14—SCSI & External Disk Drives
SCSI & the D24
Additional recording space can be made available by connecting optional, external
SCSI hard disk drives or removable media drives to the D24's SCSI port. The SCSI
interface supports Narrow SCSI-2 (FAST-20). The D24's filing system supports up to
8.4 GB of disk space per disk drive. Larger capacity disk drives can be used, but only the
first 8.4 GB can be accessed by the D24. A list of disk drives certified for use with the
D24 is provided on page 155.
The D24 works with one disk drive at a time, internal MO or external drive, and does
not record across drives. The maximum recording time therefore is dependant on the
capacity of the selected work disk. With five SCSI IDs available, up to five external disk
drives can be connected to the D24 at the same time.

Using External Disk Drives

When using external disk drives, keep the following points in mind:
• Turn off the D24 and the external disk drives before making any connections.
• For reliable operation, use only good-quality SCSI cables.
• Assign an exclusive SCSI ID to each disk drive. See "Assigning SCSI IDs" on page 156
for more information.
• Terminate the SCSI bus correctly. See "Terminating the SCSI Bus" on page 157 for more
information.
• All connected disk drives must be turned on in order to use the D24.
• The D24 checks the SCSI bus for connected devices when it's turned on. SCSI devices
that are not turned on will not be recognized and may affect performance, so make sure
that all connected drives are turned on before the D24. External disk drives that you do
not intend to use should be disconnected before turning on the D24.
• Never turn off or disconnect an external disk drive while the D24 is on.
• The work disk is selected using the Drive Select function. See "Selecting the Work Disk"
on page 161 for more information.
• New disk drives and drives that have been used to store other kinds of data must be for-
matted before they can be used with the D24. See "Formatting External Disk Drives" on
page 158 for more information.
• The recording time available on an external disk drive can be checked using the Remain
function. The disk drive must be selected as the work disk first. See "Checking the Time
Remaining" on page 38 for more information.
• Drive space occupied by unused sound files can be retrieved for additional recording
using the Optimize function. See "Recovering Disk Space" on page 172 for more infor-
mation.
• When using large external disk drives, we recommend that you backup up your impor-
tant projects to the internal MO disk drive using the Backup function. See "Copying
Projects Between Disk Drives" on page 164 for more information.
• If a SCSI error message appears on the display, see "Error Messages" on page 194 for
more information.
