Automatic Drive Spin-Down and Write

Guidelines for High Temperature or Humidity Conditions (Outside the Specified
Operating Environment)
Page 84
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.
Following the guidelines listed below can minimize the possibility of extreme
temperature or humidity conditions, causing problems with the drive.
z
Use DDS cartridges only at temperatures between 5
°
(113 F). The cartridges can be stored at temperatures down to –40
°
(–40 F). Although the storage specifications range from 5
leave cartridges in severe temperature conditions—such as in a car in bright
sunlight. Avoid extreme changes in temperature or humidity whenever possible.
z
If cartridges are exposed to temperatures or humidities outside the specified
operating environment, condition the cartridges by exposure to the operating
environment for a time at least equal to the period the cartridges were exposed
to the out-of-spec environment (to a maximum of 24 hours).
z
Place the drive in a position that provides stable temperatures. Do not place the
drive near open windows, fans, heaters or doors.
z
Do not read from or write to cartridges when a temperature change of 10
hour is occurring.
