Some things do need to be specified, like sector size. Other things, like the number of sectors can be determined from the disk being read. This in particular allows us to lump what are often described as 100's of separate formats into just one (MFM). > I am curious though ... how do you know it read it correctly?

We recommend when imaging a disk that you specify the a format -- ----- You received this message because you are a member of the Vintage Macs group.
