Floppy Disk Format Information

MAXIForm, MAXI Disk, and FreeForm can create special DOS compatible disks that offer more space than their standard DOS cousins. MAXI style extended capacity disks are transparent to DOS 3.2 and later. The major characteristics are outlined below. Total disk capacity can be adjusted by increasing or decreasing the number of cylinders.

Type	Size	Capacity	Sectors per track	Tracks per side
DOS 360k	5.25"	360k	9	40
MAXI 420k	5.25"	420k	10	42
DOS 720k	3.5"	720k	9	80
MAXI 800k	3.5"	800k	10	80
DOS 1.2 meg	5.25"	1200k	15	80
MAXI 1.4 meg	5.25"	1400k	17	82
DOS 1.44 meg	3.5"	1440k	18	80
MAXI 1.6 meg	3.5"	1600k	20	82
DMF 1.7 meg*	3.5"	1700k	21	82
DOS 2.88 meg+	3.5"	2880k	36	80
MAXI 3.2 meg+*	3.5"	3200k	39	82

*Note: DMF & 3.2 meg disks can be created by MAXI Disk for Windows and FreeForm.
+Note: 2.88 & 3.2 meg disks require a special 2.88 meg floppy disk drive and controller on your system.

Note, some systems require the driver program SMAX to read and write MAXI style extended capacity disks properly. SMAX is included with all current releases of MAXIForm, MAXI Disk, and FreeForm. You can download it here separately if someone gave you MAXI formatted disks and you cannot read them on your system.
