DAT 72/DDS-4 Product Manual
Note:
If cleaning the head does not correct a flashing LED condition, try using a
new data cartridge.
How to Clean the Tape Heads
To clean the tape heads on your drive, use only a Seagate-qualified DDS cleaning
cartridge. Seagate offers a cleaning cartridge, Model STDMCL or CDMCL, available
from http://shop.certance.com. Do not use an audio DAT cleaning cartridge. The
drive cannot recognize it.
After you insert the cleaning cartridge, the drive detects that the cartridge is a
cleaning cartridge, and loads and runs the cartridge for about 30 seconds. When
cleaning is complete, the drive ejects the cartridge.
Each time the cleaning cartridge is loaded, a new, unused portion of cleaning tape is
advanced over the entire tape path. The drive does not rewind a cleaning cartridge.
After about 30 cleaning cycles, the entire tape is used. If you insert a completely
used cleaning cartridge, the Clean LED flashes rapidly. Replace the cleaning
cartridge.
Automatic Drive Spin-Down and Write
To maximize tape and drive mechanism life, the drive automatically stops the
cylinder when no tape read or write activity occurs.
If a read or write operation occurs, normal operation resumes with no affect on the
host operation.
If tape write operations cease, a partially full data buffer may remain. After one
minute with no activity, the drive automatically writes the partial buffer to the tape.
This automatic action minimizes the possibility of lost data if the power fails.
If data to be written remains in the buffer when the eject button is pushed, the data is
written to tape before the tape is rewound and ejected.
Operating the Drive in High-Temperature or Humidity Conditions
Being faithful to the following guidelines can minimize the possibility of damaging the
drive due to operation during extreme temperature or humidity conditions (outside
the specified operating environment).
•
Use DDS cartridges only at temperatures between 5
°
C (40
°
F) and 40
°
C
(113
°
F). The cartridges can be stored at temperatures down to –40
°
C
(–40
°
F). Although the storage specifications range from 5
°
C to –40
°
C, do not
leave cartridges in severe temperature conditions—such as in a car in bright
sunlight. Avoid extreme changes in temperature or humidity whenever possible.
•
If cartridges are exposed to temperatures or humidities outside the specified
operating environment, condition the cartridges by exposure to the subsequent
operating environment for a time at least equal to the period the cartridges were
exposed to the out-of-spec environment.
