Initializing DigiDrives
Occasionally, you might want to initialize the
drives on your Digidesign system to remove all
the data that is on them. Initializing re-creates
the partition map and directory structure, im-
proving overall drive performance. It is best to
initialize drives when you are between projects,
or when the media files and other data on the
drives are no longer needed.
For more information on initializing drives, see
the
ATTO ExpressPro-Tools manual .
Troubleshooting
Occasionally, you might have problems with a
DigiDrive that you can repair on your own. The
following sections present several scenarios and
steps to take to repair them.
DigiDrive Does Not Turn On
When a DigiDrive does not turn on after you
press the power switch, you should do the fol-
lowing:
1 Make sure the ac power cord is securely con-
nected to the drive enclosure.
2 Make sure the drive is plugged into a power
strip or a wall outlet.
3 If the drive is plugged into a power strip, make
sure the power strip is plugged into a wall outlet
and that the power strip is turned on.
After you turn on the drive, the green power
LED on the front of the drive is lit.
DigiDrive Does Not Appear on the
Desktop
When a DigiDrive does not appear on the desktop:
1 Make sure the drive turns on. Follow the in-
structions in “DigiDrive Does Not Turn On” on
page 24 if the drive does not turn on.
2 Make sure all the cables in the SCSI bus are
properly connected and secured in place by
thumbscrews for wide drives or bail-latches for
narrow drives. See Chapter 3 for cable and setup
information.
3 Make sure each SCSI bus is properly termi-
nated. See Chapter 3 and Appendix B for infor-
mation on the correct terminator to use with
the drive configurations on your system.
4 Make sure each drive on a SCSI bus has a
unique SCSI ID. If you have drives with dupli-
cate IDs, one or both of the drives might not ap-
pear on the desktop. See “SCSI IDs on
Macintosh Systems” on page 16 for information
on how to set SCSI IDs. Turn the drive off and
then on to ensure that the new SCSI ID is set.
5 After making sure the drive is on, making any
cabling changes, changing drive termination, or
changing SCSI IDs, restart the Digidesign system
for the changes to take effect.
Initializing a drive destroys all the data on
the drive. Make sure you back up all the crit-
ical data on the drive to tape or another
drive before you initialize the drive.
Before making any changes to DigiDrive ca-
bling or termination, make sure you shut
down the Digidesign system and turn off all
of the drives on the SCSI bus.
