have tried different IDE adapters as well. Seems WinUAE just isnt going to work on the PC with my Amiga HD.
Not to worry, my 4GB CF arrived yesterday, so I'm using EasyADF to backup each partition to an .LHA file to the card which will suffice as a backup. I see what you mean about taking ages though, but its getting there

Thanks again for all your help and advice, much obliged

Perhaps the USB adapter is the culprit. Do you have another one?
