I am using HP Data Protector A.06.11 in my organization, with HP EML E-SeriesEML library, with 4 drives using LTO-4 tapes, and i am having some problems.

Yesterday I put 5 new tapes in the robot and formatted them. At that time, the robot got just those empty 5 tapes with empty space. (all the rest of the tapes are red, or with protection)

Today in the morning after the night (1 backup run at night), and 2 of the new tapes are red (the properties are):

Writes : 2
Overwrites : 1
Errors : 9

I format one of them, and check for each drive if the tape become red, no one of the drives do it.

In the main pool properties, in media condition got:

Valid for : 36 (months)
Maximum overwrites : 250
