Always get the same error in Backup Exec 2010

Everytime I try to catalog one of our old DLT tapes - I get the 0xe0000900 error.

"..The requested media is not listed in the media index and could not be mounted. To add the media's catalog information to the disk-based catalogs, run an inventory operation on the media and resubmit the Catalog operation.
Final error category: Backup Media Errors"

Symantec support mentions something about if Backup Exec was on 1 server, then moved to another - and created with a certain version  blah blah blah - (typical BE obscurity)

Can anyone shed some light on this for me ?
I have about 200 old tapes I need to restore and move to LTO tapes - I can catalog / restore a single one ...  I have removed the chackmark which forces the software to request all media in a set - that is disabled now - to no avail.

Thanks Again

were these backups taken directly to tape or first to disk and then to tape?

some were taken directly to tape, others from disk to tape - is this error telling me those people did the process completely wrong ?

i think so, normally when you do backup2disk2tape, you do so using a special policy included in BE,
I've seen the problem you are facing a couple of times when people did a backup of the "bkf" files that were being backed up to disk.
so basically you have BKF files in BKF. this would be a problem.
I'm not sure that this is your problem, just saying;)

I havent been able to find a set of media where the backups were not done from disk to tape - as all of them give the same error - our archiving company is giving me 200 tapes next week... I hope I can see some productivity.  Subjectively, what is your overall opinion of BE ?  I hear nothing but negative, but want to ask people who have to deal with it daily, not just pass what they heard.

Thanks for Your Help

The answer given wasnt a complete resolution, but did offer insight - which is helpful.
Backup Exec is by far the best solution to backup your servers.
I have no problems with it. anymore that is, it takes a while to learn all the pitfalls and sometimes it's the hard way with unusable backups and such.

I can only recommend that you do regular test restores to see if the backup is good.

OK - Thanks Buddy -

So many people pass judgement on things or give reviews on something & have no business doing such - I wanted an experienced opinion from someone who is "in the trenches" using it everyday.
