Problems During Backup/Restore Operations

1The TapeAlert message or backup log shows, “The operation has stopped because an error has occurred while reading or writing data which the drive cannot correct.” A media error occurred during write or read operation on the tape drive. Review the troubleshooting procedures to ensure that the proper SCSI cabling and termination practices are being followed. Restart the backup if any changes are made to the SCSI cabling or termination or if any cables or terminator are unplugged then re-plugged.

This message may also be seen with, “The tape is from a faulty batch or the tape drive is faulty.” or “The tape is damaged or the drive is faulty. Call the tape drive supplier helpline.” If either of these messages also appears, use a good tape to test the drive. If the problem persists, call the tape drive supplier helpline.

2Remove the data tape and insert a cleaning cartridge. After the cleaning cartridge ejects reinsert the data tape and restart the backup. If the backup succeeds, the problem is resolved.

3If the backup fails, try to isolate the tape media vs. tape drive. Use diagnostic software to perform a write/read test of 4GB of data. The current data on the tape WILL BE OVERWRITTEN AND ALL

PREVIOUSLY WRITTEN DATA ON THE TAPE WILL BE DESTROYED.

Use a second tape for the diagnostic test. If the diagnostic test passes on the second tape, use the tape for the backup process and remove the first tape from the backup process.

4If the diagnostic test fails on the second tape, insert a cleaning tape into the drive and repeat the diagnostic write/read test. If the diagnostic test passes on the second tape, the problem is resolved.

5If the diagnostic test fails on the second tape, the tape drive may be bad. Use the diagnostic software to perform a write/read test on the first data tape. The current data on the tape WILL BE OVERWRITTEN.

ALL PREVIOUSLY WRITTEN DATA ON THE TAPE WILL BE DESTROYED. If the diagnostic test passes on the first tape, the problem is resolved. If the diagnostic fails on the first tape, the tape is bad and should not be used any longer.

6If a second data tape is not available to test with the diagnostic software, but a cleaning tape is available, insert the cleaning tape. Remove the cleaning tape after the cleaning tape ejects and restart the backup. If backup is successful, the tape drive and tape are satisfactory.
