Max Disk Formatter

Max Disk Formatter is a utility program used to format floppy disks, and was often used to format them to nonstandard (larger) sizes. Disks formatted by MDF cannot be used in a conventional manner, even with the standard format size, because of the non-standard file system.

As floppy disks are no longer widely used, this program is now obsolete. However, it has one feature that is useful for old computers: it can format diskettes which cannot be formatted by the standard DOS format program.

Notes

1. If BIOS has an information about 5.25 inch drive as A: and not as B: the program may attempt to use an incorrect format.
2. Norton Disk Doctor and similar programs do not understand MDF's format, and may try to format the floppy back to a standard filesystem, thus rendering it unusable.
