I am working with Networker 6.1 on a Windows 2000 Server. In the last days I regularly get one of the following error messages:

Apr 11 12:29:59 backup-machine: NetWorker media: (warning) \\.\Tape1 writing: Data error (cyclic redundancy check)., at file 2 record 613 Apr 11 12:29:59 backup-machine: NetWorker media: (notice) 8mm AIT-2 tape 000263 on \\.\Tape1 is full Apr 11 12:29:59 backup-machine: NetWorker media: (notice) 8mm AIT-2 tape 000263 used 39 MB of 50 GB capacity Apr 11 12:29:59 backup-machine: NetWorker media: (warning) verification of volume "000263", volid 1515195649 failed, read open error: No error Apr 11 12:29:59 backup-machine: NetWorker media: (notice) verification of volume "000263", volid 1515195649 failed, volume is being marked as full.

Afterwards the tapes are marked as full, the drive is not able to unload the tape (I have to do it manually). It happens to both drives tape0 and tape1 . First it happened only to drive \tape2, then I disabled it, then it happened to \tape0 as well. In the event viewer is the following message: The device \Device\Tape1 has a bad block.

and in the log file:
04/26/05 11:37:21 AM nsrd: media info: unload error for jukebox '[email protected]' detected. Retrying

The Networker monitor shows : tape1 read open error: No error

We use a Qualstar TLS-4222i Jukebox with 2 SONY SDX-500C drives.

Is it a problem of the tapes, of the drives or what else ?

Any help appreciated.

Thanks

Hilde Gerlach
