Media is unrecognized.

I have a HP DLT VS 80 Tape drive and did not notice this till recently. All my tapes are throwing the following error message when trying to restore:

Media is unrecognized.

The media in drive 'HP 1' is written in an unrecognized format. Erase the media to make it usable.

I also notice that when a tape is loaded into the drive it either Lists ALL the Tape drives in the "Online" section in the "Media Location" section of the "Media" tab, or it lists <NONE>. Possibilly indicating that it does not recognize the tape in the drive.

I need to perform a restore on a Mailbox store and this is very urgent and am running out of things to try.

Maybe this may be a result of the problem that I am experiencing? See below for what I am referring to:
I also am getting a weird issue that I had already posted, but did not try to resolve. Basically, when I reboot my server it hangs during th POST screen when it reaches the SCSI ID screen.
I will try to resolve the hanging boot tonight. (referring to http://www.experts-exchange.com/Storage/Q_21273499.html). As indicated in the article I will shut down the server and disconnect and then reconnect the SCSI cable.

However, I find it highly unlikely that the problem with ALL my cartridges not being readable is as a result to the issue above. Or maybe.

Please assist me with this ASAP as this is urgent.

Thanks in advance.

Shutting down and disconnecting and reconnecting did not resolve the hanging of boot up.

Also, after a fresh boot, and when I insert ANY media, <NONE> appears.

If the server does not POST through the SCSI bus scan fully, that is the first issue to be resolved.  I would see if the tape drive can be attached to a different SCSI controller
(preferably in a different system) just for the purpose of determining whether the SCSI scan can be completed with it attached to the chain.

There are the usual SCSI culprits, ID setting, cables and termination to be checked upon.  If you have another SCSI device that can be attached to the culprit server, this should point you in the direction of which component to concentrate on, the SCSI interface, the cables ot the tape drive.

At this point, I would focus on the hardware and attempt to determine whether it is fully functional or not.

I hope that helps.
