I got an error when trying to do NT backup by selecting tape drive. The error is :
<required media missing>:- "There is no unused media available with the selected type. Add unused media or click cancel to select another type. Note: It may take up to 60 seconds for removable storage to recognize new media".
This problem has been raised before but the fix did not work for me.
I solved the problem by using BLUE tape instead of BLACK ones.
Black ones are all labelled ultrium 1 100G
Blue ones are hp 200G Ultrium 1 C7971A.
One server is using Ultrium 1 intrenal scsi drive and the other is using external ultrium 2
Both have exactly the same driver installed.
Does anyone know what the 'rules' are for using tapes like this between these drives.
It looks as if the ultrium 2 will read the 100G tapes but not write / recognise them for back up and that the ultrium 1
will use either ? is this true?

The black tapes are either IBM or Segate.
I have found by experiment that the black tapes which cause the problem on the ultrium 2 external drive will work on the ultrium 1 drive BUT are recogonised as NEW unformatted media. The ultrium 1 drive accepts these black tapes and backups ok. I will try the backed up tapes (Black) on the ultrium 2 drive later to-day. There must be some 'rule' which explains this situation. I thinl it may be associated with the capacity of the tapes. All the tapes are marked ultrium 1. Rgds eddie

You can also see at http://h18006.www1.hp.com/products/quickspecs/11739_div/11739_div.html it says "The Ultrium 460 tape drive is fully read and write compatible with the first generation of Ultrium tape drives." so there's something strange about your black tapes.
