InitDisk
(ver 5)
Freeware


InitDisk does not require installation.  If you click on the icon,
it will start the program.  If you already have a USB drive 
inserted in the PC, the program will prompt you to remove it and 
then re-insert it before format can take place.

For maximum compatibility, InitDisk formats with a MBR and FAT 
(12/16/32) partition.  Its maximum drive size is 2.2 terabytes.

If you run the program from the Windows Command Line, you can 
opt to include the parameter "freedos".  This will not only 
reformat the USB drive, but it will also install a minimal 
FreeDOS operating system on the USB drive.
