I'm not sure I understand. Is this a file system named "RAW"
Generally when some of my Floppie go bad ( i can't access it and it says" can't access the floppy device .the floppy is not formated do you wan to format it now") and i try to format it (in windows OS's) when i say format "a:\ " it shows the current File-system is RAW....and the new the new file system will be FAT...i am not sure RAW is a file system ...my guess is if the system detects no file system in the floppies it says it has RAW file System..simply formatting will change the file system to FAT

On Windoes OS's (Windows 98/2000/XP)

Go to "Command Prompt " (Start ->Run-> type"Command" press enter)

Symply type there on the command prompt "Format a:\" press Enter

or

open My Copmuter ..right Click on "3 1/2 Floppy "a:"" icon ..select format.

If it says "Bad Sector 0 " or " cannot read form the specified device" ..that means you will have to get some third party software.....they sometimes are able to still format the floppies......

i have stopped using floppies a long time back...IMHO it is the most unreliable data storage media...I used to have a Software called "HDcopy" which used to format these kind of floppies which windows is not able to format .......

When i buy new floppies they are pre-formatted with fat filesystem..so i have never seen a new floppie having a RAW File System...or maybe i always buy pre-formatted floppies....

type in winfile
oo dear something from the history (Windows 3.11 era).....i had almost forgot we had something called winfile still....
