Hi Alan, I'll reply when possible, I'm flat out on clients work plus trying to help as much as possible on WAMUG. I need a break, some food for my brain, some sleep to keep my body going. I’ll get back to you sometime.
Disk Utility is the program you use for creating a petition and removing a petition.... But you have to do this absolutely correctly. DON'T mess around without knowing exactly how to do this or you will erase the whole drive. From what you mentioned below: > DU is scary here - it says “to erase and partition the selected disk …” etc You are not doing it correctly. - You can’t partition a partition, you can only partition the hard disk that contains the partition. As I’ve said above, I will reply with instructions when I can find the time to prepare thorough set of instructions.
