Hi Bill.

Drive is fine. It was a toddlers jam sandwich which knackered the disk (disk not been in drive though). Have had a very useful email from "Icecool" giving good insructions about running OSmaker in DOS so will try that when I get my hands on a old 95 or 98 machine. Their a bit few anf far between these days though. Will post how it goes.
Thanks for your suggestion though.
