Problem 

When adding a tape library to NAKIVO Backup & Replication, the following error message is displayed:

Data in the (X) tape cartridge cannot be discovered.

The (X) tape cartridge block size is different than the block size of the (Y) tape device.

Background

To access content on all the tape cartridges of a tape library, all tapes should have the same data block size. The above error is displayed when a tape cartridge with backups created by NAKIVO Backup & Replication is added to the product again as part of the tape library that has a different data block size. To solve this problem, use one of the solutions below:
