Log:
[EXT2]
Add the ReactOS famous... hack? fix? whatever? already present in FastFAT,
NTFS...:
When accessing a floppy disk, our floppy storage stack can return that the disk
type is unknown (some would say it's legit - see comments in FastFAT) and will
also return a disk sector size of 0.
Then, when trying to read the floppy disk with said size, everything goes wrong
(null length read is never a good thing). So, as in any other FSD in ReactOS,
for disk sector size to 512 bytes in this really specific case.
This fixes BSOD when having a floppy drive in ReactOS (whatever its filesystem).
