Quarter-inch Cartridge (QIC) Tape Drive Troubleshooting
The QIC drive is replaced as an entire assembly, but before replacing it you must make sure
the problem is caused by a QIC hardware failure. This means you must rule out problems
caused by the tape media or dirty heads.
Use the following sequence to isolate QIC drive problems.
1. Try cleaning the tape heads and see if the problem is solved.
2. Determine if the problem is media-related by installing a new QIC cassette and retrying
the failed operation.
3. If the preceding steps have not solved the problem, replace the entire QIC drive.
4. Check system operation to make sure the problem is solved.
