When I use Nero, it 'complains' that this is a non-standard way of writing--completes the process, but when I come to re-use the disc, once again it seems to be unrecognised. I couldn't find an option in Nero to format the drive either.
Thanks for replies... haven't had time to try the various suggestions yet, but will work through them when I have time.
Cheers for now...
