From f79fbfbb61a69b7b0dae11e4a7d035e7803ec699 Mon Sep 17 00:00:00 2001 From: Pierre Schweitzer Date: Sat, 13 Feb 2016 09:16:45 +0000 Subject: [PATCH] [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).
