Thanks for your responses.
I can't remember the exact message - 'The disk is write protected, remove the disk'-nothing else of import - nothing about this disk is unformatted etc etc.
What I am using is the Pinnacle Instant Backup which came with my computer - nothing very sophisticated no doubt but should it not work?
My DVDs are + (I wanted to see if they would work) but I tried CD-RW without success, same message.
In my Windows XP Home Edition: The Complete Ref. page 880 it says Recordable CD-R and RW disks do not need to be formatted!!
If needed how would I format them?
Hope this helps.
