From: Paolo Bonzini <[email protected]> The sector count is stored in the partition and hence must not include the sectors before its start. At the same time, remove the useless special casing for 1.44 MB floppies. This fixes fsck on VVFAT hard disks, which otherwise tries to seek past the end of the disk.
