Bypassing media descriptor byte check in XP

March 11, 2011 at 14:39:33
Specs: Windows XP
I have still couple of hundred old DOS and Win95 formated floppies from which it would be nice to recover some data, without going back to DOS or Win95 :) Thus, it would be nice to know if there is any "easy" way to bypass the media descriptor byte check from bios parameter block in Windows XP. With easy I mean e.g. already existing third party floppy drivers working also with usb floppy drives or some detailed information how and where the check is done.

Of course there are few workarounds for the problem such as using the disc sector editor to edit the MDB to correspond the format type on each floppy...but, since there are several floppies to go through...:)

On the other hand, there is a 3-mode floppy controller driver available, but at least for me the VIA 3-mode drivers did not work and provided only BSOD with the USB floppy drive...and I am not even sure that this driver suppors "RAW" mode (the case where there is no media descriptor byte set on the FAT).
