I would like to convert my homebrew system from 8" SSSD to a 5.25" format. Which format should I use? Has anyone ever compiled a list of formats? I assume a format description would include the following: Recording format: IBM (SD or DD) or Apple. This would also include definitions of gaps, CRCs, address marks, etc. These are the truly controller- dependent characteristics. Number of sides and tracks: These are drive-dependent characteristics. Sector size and sectors/track: Controllers can almose always be programmed for this. CP/M filesystem parameters: Physical sectors/sector, allocation group size, directory size, and the other Disk Parameter Block junk. Strictly software-dependent. Has anyone ever seen a list.
