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?

There's also a list of colours at http://en.wikipedia.org/wiki/Linear_Tape-Open, I'm not sure what the black tapes you have are, is there a part number on them?

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.

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
