Handling the DigiDrive
You need to use reasonable care when you han-
dle a DigiDrive. Though the drive is ruggedly
constructed, it has delicate internal mechanisms
that can be damaged when handled in an incor-
rect manner. The following lists contain tips for
handling and caring for the drives attached to
your Digidesign system.
When the drives
are not operating:
◆ Be careful not to drop a drive as you move it
from one system to another.
◆
Keep the area around the drives free of dust
and dirt.
◆
When you stack the drives, limit the stack
height to four drives. This helps to prevent the
stack from tipping over.
When the drives
are operating:
◆
Do not shake or jar the drive enclosures. This
can damage the read/write heads or the mag-
netic coating on the drive platters.
◆ Do not turn off the power to a drive while you
can see the icon on a Macintosh desktop. This
can cause directory structure problems and
might create incomplete files.
◆
Do not turn off the power to a drive while an
application is reading data from or writing data
to the drive. This can cause directory structure
problems and might create incomplete files.
◆ Never disconnect SCSI cables or the SCSI ter-
minator while the Digidesign system and the
drives are running. Shut down the system and
turn off the drives
before making cabling
changes.
SCSI Configuration
Requirements
As you add a DigiDrive to your Digidesign sys-
tem, you need to be aware of the Digidesign re-
quirements for installing the drives correctly.
These requirements include:
◆
Laying out drives on the SCSI bus
◆ Cabling the drives
◆
Setting the drive SCSI IDs
◆
Terminating the SCSI bus
The following sections list the requirements for
installing a DigiDrive and configuring the SCSI
bus. If you fail to meet all of the requirements,
your DigiDrive and Digidesign software might
not function properly.
Do not open a DigiDrive enclosure; there
are no user-repairable parts inside. Opening
the enclosure voids your Digidesign war-
ranty and prevents you from having the
drive mechanism repaired without charge.
