Thanks for the info Jerry. I get read errors, data errors, density errors, sector addressing errors. Probably every kind of error xxdp can give :) Please see this link if you are interested: https://aaronsplace.co.uk/private/o/48859c14f6a619a5316d6af37d60579c.txt I will take a proper look through the field manuals tomorrow, and also try what you suggested with trying the same media in both drives. Thanks, Aaron.
