Another thing to deal with in a proper disk copier. I want to update the creation time on an AmigaDOS volume when copied to keep from confusing AmigaDOS if both disks are mounted at once. How do I do this? Is the rootblock found by (highest block # - lowest block #)/2, rounded? That is, is the rootblock on a floppy always block 880? How can I avoid accidentally modifying a disk if it is NOT an AmigaDOS disk? Turn the disk-validator loose on the source disk and update the destination if it is considered valid by AmigaDOS? Some other method? Deven -- Deven T.
