URL: http://svn.reactos.org/svn/reactos?rev=70725&view=rev 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).
