Subject: Re: Looking for disk formats

I am also wondering about disk formats.  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.
