This barcode does not look right to me, and the length of it may exceed the number of characters that DP allows for Bar Codes
I would suggest that you go into Properties for your Library, and under the 'Control' tab, you disable 'Barcode Reader Support', click OK and Apply. This will mean the bar code is no longer being read
Data Protector uses a Media ID, to identify media needed for the Restore, visible by getting Properties for any media, and clicking on the 'Info' tab, it does not use the Bar Code, so I don't see turning off Bar Code Support as causing a major problem. It may be a good idea to right-click on the media, and do a physical device scan to update the IDB. This shoud take no more than 60 seconds per media
