Operation
Unloading a Cartridge
Caution. Do not push the eject button while the Drive Status LED is ON. Otherwise, you may
lose data.
Be sure the drive-status LED is not lit. Then unload the cartridge by pressing the eject button. For the
location of the eject button, see Figure 10 on page 21. After you press the eject button, the drive
automatically flushes the drive buffer to tape, updates the system log, and rewinds the cartridge
before ejecting it.
NOTE: Several seconds may elapse between the time you press the eject button and the time the
cartridge is ejected. Do not power down the tape drive or the host computer during this time.

Initializing a Blank DAT Cartridge
When you insert a blank cartridge into the drive for the first time, the drive takes about 10 to 12 sec-
onds to determine that the tape is blank. The drive automatically initializes the tape as soon as it
receives a Write command from the host computer. Initializing a blank tape takes about 30 seconds.
While a tape is being initialized, the normal write operation continues until all internal buffers are
filled. Ejecting the cartridge before the initialization is complete causes the procedure to abort. The
initialization restarts from the beginning the next time a Write command is received.
NOTE: The data buffer of the drive is flushed to tape if a Rewind command is issued, if the eject
button is pushed, or if a delay in SCSI activity occurs. By default, the delay before the flush
occurs is set to one minute. However, this delay time can be modified by the host application
using a Mode Select command.
