2.6.0: vvfat driver generates bad FAT entries
Status in QEMU:
The vvfat driver sometimes generates entries about which file system
checking utilities generate complaints.
For example, dosfsck will complain that the volume label entry has
non-zero size. ScanDisk from Windows 9x complains about invalid dot
(".") and dot-dot ("..") entries in directories and also about invalid
long file name entries. MS-DOS ScanDisk also often manages to find
"lost clusters" on the drive.
Tangentially: qemu-img convert fat:test test.img doesn't seem to work
-- it generates an 504MiB of zero bytes and hangs. qemu-img map
fat:test generates an assertion failure. Having qemu-img working might
have helped with debugging the above issue.
