Tinstaafi's solution worked for me. If he cannot find the programme to which he refers, I can - he sent me a copy! (Thanks Tin). Email me if req'd.
A caution on using 'manufacturers' progs' to install, though, my Seagate install somehow trashed my C: drive. My eldest lad (who like all kids is FAR cleverer than his dad) told me the first thing to do with such a programme is to bin it!
Beware also that some files will NOT copy over under Windows if they are in juse by Windows. Either revert to DOSCOPY or if you are a cynic like me, use your 'Emergency' Win3.1. It has saved my electronic life more times than I care to think.
