Possible Cause
A lost leader is dropped.
Power or signal cable is
not seated.
Nonembedded controller
is not properly seated.
DLT drive is not firmly
connected.
Tape is write-protected.
Possible Solution
Check every tape cartridge that has been
used in the DLT drive. After you locate
the bad cartridges, dispose of them. As
soon as a good tape drive is installed
with a bad cartridge, the tape drive will
drop its leader, indicating that it needs
replacing.
Check the power and signal cables to be
sure they are properly seated:
1. Push the cables to be sure that they
are tightly connected.
2. If pushing in the cables does not
solve the problem, remove the
cables and then firmly reconnect
them.
Check the controller to be sure it is
properly seated:
1. Push the controller to be sure that it
is tightly connected.
2. If pushing in the controller does not
solve the problem, remove the
controller, and then firmly place it in
again.
Check the DLT drive to be sure it is
properly seated:
1. Push the DLT drive in tightly.
2. If that does not correct the problem,
completely remove the DLT drive
and reseat.
1. Remove write protection.
2. If the tape still does not work, try
another tape.
