Hi Jon,
Therefore I've various possibilities:
0 - To Check connections ( though the problem only occurs with the tape 04)
1 - To update the soft from my PowerVault ( from dell )
2 - To Cleaning heads
3 - To change the tape 04
How can I check the state of de tape surface ( any command )? or to delete
contents, re-initialize the tape...
Best regards,
