All this has been done. By naming a tape I'm referring to running a label job. The tapes are supported by the hardware and the hardware is supported by BEWS.
I've tried it all.
I run a "label job" on each tape, one at a time. The first tape that ran a "label job" becomes in the device manager inside BEWS. If I run two jobs at the same time (the reason for two tape drives) one of them will fail out saying the media is overwrite protected even though its media is still in scratch. When checking into the error it's because the first drive thinks it's the same media as the last labeled media in the second drive, which has taken the name of the first labeled media.
Confusing, yes...
So then I run two "label jobs" and run a backup job to tape A, eject, run a backup job to tape B, eject. Insert both tapes after than, run an inventory job on each tape and only one tape is recognized as the first job run the other becomes again with the drives thinking they both have the same tape.
I open removable storage in windows and behold, the media in the drives are listed correctly and no amount of reboots, service restarts or jobs within BEWS will cause BEWS to report the same results as Removable Storage, or even report two seperate tapes.
So, Windows Removable Storage = works.
BEWS = doesn't work.
