Well it's cracked!
Tbone's idea of backing up worked. I simply used W98 own backup and with compression backup D: to C: It was a whole 1.7gb but it compressed to 999mb.
That's the good news. The not so bad news is that my new D: drive has Disk_Vol 2 in front of it and I can't seem to get it to plain D: Any ideas on that? I suspect I would have to deal with in DOS - but not sure. Anyway everything drop back home quite nicely.
Tbone - Feline - Dimsim. Thanks for taking the time and trouble to assist. It is very much appreciated.
Bye
