Error Code Cause and Action
A
Degraded operation. The tape drive determined that a problem occurred which degraded the
operation of the tape drive, but it did not restrict continued use. If the problem persists, determine
whether the problem is with the drive or the media.
Note: The drive is usable, though the Single-character Display continues to indicate an error and
the Fault light flashes. The error code may clear when you cycle power to the tape drive or place
it in maintenance mode.
To determine if the problem is with the drive hardware, or the tape media, perform the following
procedures:
1. If possible, run the tape cartridge in a different drive. If the operation in the other drive fails
and
6
or
7
displays, replace the media. If the operation succeeds, run the Test Cartridge
& Media diagnostic (see “Function Code E: Test Cartridge & Media” on page 3-17).
2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully, clean
the failing drive and run the drive diagnostics (see “Cleaning the Drive Head” on page 3-7
and “Function Code 1: Run Drive Diagnostics” on page 3-10).
Once you begin this test, the diagnostic test begins the loop sequence. Time the first loop by
pressing
Unload once to stop the diagnostic test after the completion of the first loop. Then
record the time that it takes for the test to complete. Compare the recorded time with the
"Approximate Run Time". If the test runs successfully but the execution time is longer than the
"Approximate Run Time", run “Function Code F: Write Performance Test” on page 3-17. If the
Write Performance Test fails, replace the media and exit Maintenance Mode. If the drive
diagnostics run successfully, perform the operation that produced the initial drive error.
3. If the problem persists replace the drive.
If it is not possible to run the tape cartridge in a different drive, perform the following
procedures:
1. Clean the failing drive and run the drive diagnostics (see “Cleaning the Drive Head” on page
3-7 and “Function Code 1: Run Drive Diagnostics” on page 3-10).
Once you begin this test, the diagnostic test begins the loop sequence. Time the first loop by

Write Performance Test fails, replace the media and exit Maintenance Mode. If the drive
diagnostics run successfully, run the Test Cartridge & media diagnostic (see “Function Code E:
Test Cartridge & Media” on page 3-17).
2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully,
perform the operation that produced the initial drive error.
3. If the problem persists replace the drive.
C
The tape drive needs to be cleaned. Clean the tape drive. See “Cleaning the Drive Head” on page
3-7.
The error code clears when you clean the tape drive or place it in maintenance mode.
