I have nothing to format the disk ... no X-Copy 3 or anything like that.
I have been using a BBC HD disk as my Player Manager Data Sisk, and it now has File Error... what you said above about DD could explain why! (thanks for the info).
There are no computer shops around me that sell DD disks ... plus I need to format it.
Anybody got a "X-Copy 3" ... thats the best one .... or "X-Copy 2" ... that had a disk doctor on it!!!
