Hello,

I have a fast growning list of FROZEN media in one of my robots, 
on one of media servers to be correct. 
There is no read/write/positiong errors in db/media/errors. 
Before became unusable tapes HAD USED for backups and HAD 
6-80 GB of data on them, i.e. was active.
When I tryed to read contents from frozen tape Netbackup 
reported:
No report available.

cannot read media header, may not be NetBackup media or is corrupted


I tryed to track if there is a bad tape drive, and couldn't 
do it. All frozen tapes were used in different tape drives.  
After bplabel'ing the frozen tape it can be used again.

bptm log file contains:
log.091601:16:31:06 [3553] <2> write_backup: media id 003615 mounted on drive 
index 3, drivepath /dev/rmt/5cbn, drivename uback-ap9-1_4
log.091601:16:31:08 [3553] <16> io_read_media_header: block read is not a 
NetBackup media header, len = 1024, media id 003615, drive index 3, data is 
unknown
log.091601:16:31:08 [3553] <16> write_backup: non NetBackup media found in 
drive index 3, FREEZING 003615

Anyone seen this before? Any ideas?

Any help will be appreciated.
