Full height drive: Tape spooled off supply reel
About this task
Note: If the cartridge in the drive is an INPUT tape that contains ACTIVE or 'ONLY COPY' data (there is no
backup), eject commands that are issued at the host fail to unload the tape, and power-cycling the drive
fails to eject the cartridge, make no further attempts to unload this tape. Call Technical Support and open
a PMR if one is not already open, to initiate the process of sending the drive with the loaded cartridge in
for recovery.
Procedure
1. With the front of the drive facing you, pull an arm's length of tape out of the take up reel from the left
side of the drive.
2. From the take up reel, thread tape around the rear of the tape path and over the head and rollers on
the left side of the drive.
3. Set the drive on its left side with the head and tape path facing up.
4. Moisten a cotton swab with water and wet approximately 13 mm (0.5 in.) of the tape end and feed it
onto the supply reel (inside the cartridge).
5. From the bottom of the drive, insert a 2.5 mm offset hex wrench through the bottom cover access hole
and into the reel motor axle.
