Backup Exec 11 can't read tape

I am attempting to restore a tape made with BE11, when reading in tape drive in another server, seemed to automatically change the media label, now I can't see the contents, I know that nothing was written to this tape since it was last backed up. Is there anyway I can get to read the data off this tape?
MS Backup (included with Server 2003) sees that this tape was last used on the date it was last backed up but says unrecognizable format. BE11 sees a media label which it assigned but when trying to catalog the job completes almost immediately and no data is visible.
Please help, this is very urgent, I would have assigned an even higher points score to this question if it were allowed.

The bad news is - getting past LEOT is impossible without an altered drive.

The good news is that altering the drive is relatively straightforward, so you shouldn't have any problem finding a bureau that can do it.

When you say " I know that nothing was written to this tape since it was last backed up" is this because the tape was write-protected?

If you have a linux machine handy, then you could read the tape raw using dd, and see how much data is physically on the tape - if it's only a couple of blocks, then the tape has actually been overwritten with a new media label and to get the data off past LEOT (Logical End Of Tape) will require specialist help.

No, the write protect tab wasn't closed but I'm not aware that BE11 would automatically overwrite a new media label without warning.
Although I have access to a linux machine (ubuntu 8.1.3) I would know if one can obtain drivers for this tape drive (External HP DAT72 USB) I shall look into this first and post my next comment after I have attempted to connect the drive to it.
In the worst case scenario where the LEOT was written how would it be possible to read past this.

Hopefully it won't come to that...

What does altering the drive mean? reprogramming the flash eprom on the drive? I have a spare DAT72 drive I could afford to risk in order to achive that.

I don't think you could alter the EPROM unless you had access to the original firmware source code. Some bureaus may have done this - I believe, for instance, that Vogon (now Ontrack) had access to Quantum's firmware for DLT drives and was thus able to get modify a DLT drive to enable it to get past LEOT on DLTs - but no, it's a different mod I had in mind. I run a recovery bureau and have done this myself, so I'm sure I can't be the only person to have figured it out.
