I had this problem when trying to overwrite tapes that were previously
used with Backup Exec. I was able to get around it by checking the MTF1
box in "Allow Media Overwrite" in the Media tab of the Media Server
Configuration (whew!). This is in Win2k, so your implementation would be
somewhat different, I'm sure.

Hope that helps,

Subject: [Veritas-bu] DLT Tape Containing MTF1-format data


I am running Veritas Netbackup DataCenter 3.4.1 patched at NB_34_2.  I
have DLT7000 drives in an STK9710 which were just upgraded to V106
microcode yesterday.  I put several DLT tapes back in the robot for
reuse and received an error in the logs that reads:
 
    FREEZING media id 001767, it contains MTF1-format data and cannot be
used for backups.
 
Has anyone ever seen this before or know how to deal with it?
