Thanks for all the input - but I am beginning to understand why 99.9% of users don't back up their disks!
Managed to get hold of a copy of Adaptec Easy CD Creator version 4 - and it does indeed make a back up - the only problem is that I can't restore it, because it uses a DOS programme to restore - and the system doesn't recognise the CD-Writer under DOS. Grrr!
Will keep persevering - there has to be an easy solution (but I'm not quite there at the moment).
Will report back when I do get there - there may be quite a few ppruners out there who could use a backup ...
