Problem with error V-79-57344-33992

I have an error that I have never encountered before.  V-79-57344-33992 : The backup storage device has failed. 

The knowledge base instructs me to delete the B2D disk within Backup Exec, but, as this happens to be my monthly full backup job, there are multiple parts connected to this folder.  To keep track, I thought I would create another folder on the disk, then within Backup Exec, and as the delete process prompts me, repoint to the new folder.

Unfortunately, I get an error when I try to re-point.

Any ideas?

Thanks,

Rick
