I don't really nderstand the question
First, any questions about Hardware should be directed to that support group, we just don't have access to that kind of information
I did go out and 'google' HP Ultruim Tape part numbers
http://www8.hp.com/us/en/products/storage-media/product-detail.html?oid=4153086
3TB tape
p/n C7975A
There is not 1TB capacity tape
LTO-4 - 1.6 TB capacity
p/n C7974A
I don't have a tape drive attached to my system, but Belarc Advisor may tell exactly what your tape drive is. You can also check Device Manager -> Tape Drives if library is attached to a Windows system
There is also the LIbrary and Tape Tools utility
Data Protector Tools, like 'devbra -dev' will only tell you 'LTO'
