If I remember correctly on a 1.4 MB floppy the maximum data capacity was 1.38 MB. It is a situation analagous to memory sticks - 8 GB capacity, maximum data storage about 7.7 GB.
How much data are you trying to cram onto this floppy ? And is there some reason you cannot use a higher capacity medium - CD or USB stick ?
I don't know of any way to 'unformat' a drive except through a fault condition. And if you succeeded, when you tried to write to it either the system wouldn't recognise it as a drive or you would get an error message saying the drive needs to be formatted before you can use it.
im trying to get an iso thats ~1.4mb onto a floppy so that i can make one of my older computers useable in the 21st century. it does have usb ports, but for some reason they weren't properly installed, and i have no cds that can be used. hindsight-wise, i should have written "how do i completely erase all data on floppy drive, including formatting."
edit: im trying to install a kolibri iso onto the floppy disk, which is supposed to work...
