No media recognized in the tape drive
I have Backup Exec 2012 and a USB HP DAT 72 drive for backup connected to a HP Proliant Server on Windows 2008 Server Standard R2. The backup drive only allows 1 tape. I use 5 tapes: from Monday to Friday.
Although there's physically a tape in the drive, the tape isn't recognized by Backup Exec. In the "Storage" tab, it's written "No media" in brackets besides "Tape drive". When you double click on the tape drive and goes to "Media Properties", it's written "There is no media in the drive". Because there's no media recognized, I can't erase the tape as the option is grayed. I tried to run the backup manually to test, but I get the error: "The media in drive 'Tape drive' is written in an unrecognized format. Erase the media to make it usable." So it becomes an infinite loop as I can't format the tape because Backup Exec doesn't detect any media in the drive and the option to erase is unavailable.
I tried with several tapes: Friday, Monday, Tuesday, Wednesday, Thursday, Week 1. The issue remains the same.
Does anyone know how to fix this issue? Are all my tapes or drive broken?
