Catalog Error: V-79-57344-33994 - The data being read from the media is inconsistent.

Hi

First of all please update if catalog is failing in 20 min then is it failing with byte count or with O byte count.

Also would like to suggest check the statistic of tape drive and tape which is been cataloged and in statistic look for hard read ,write error if there are any please clean tape drive once 

Also you can duplicate data from tape to disk as this would recreate the catalog and data would be written to disk and see how that goes and if that fails too with byte count then could be an issue with data on tape which would be corrupted .

Lastly if you don't I intend to duplicate backup on disk you can try the steps in order given in link below and see if that helps

Thanks

How can he duplicate to disk when he cannot see any backup sets???

I've a little update:

The restore and cataloge is from a LTO5 tape.

Now I tried it with a LTO3 and 4 tape -> successfull!

There is a problem with our LTO5 tapes... We have 3 LTO5 tape loader. I also tried to cataloge a tape from loader 1 to catalog it in loader 2 and 3 etc.

Could it be that loader 2 and 3 are LTO4 tape drives and not LTO5 tape drives?  This will account for their inability to read LTO5 tapes.

We have total 7 loader. One LTO3, 3 LTO4 and 3 LTO5.

I tried to catalog LTO3 tapes in a LTO3 loader - successfull.

I tried to catalog a LTO5 tape in every LTO5 loader with no success.
