Thanks for reporting this bug. The vvfat block driver is not actively
maintained, but you can help us track down this bug:
Since it used to work in QEMU 1.4.1 you could use git-bisect(1) to
identify the commit that broke vvfat.
http://git-scm.com/book/en/Git-Tools-Debugging-with-Git#Binary-Search
https://www.kernel.org/pub/software/scm/git/docs/git-bisect.html
http://code-worrier.com/blog/git-bisect-basics/
Something along the lines of:
$ git clone git://git.qemu.org/qemu.git
$ cd qemu
$ git bisect start
$ git bisect bad master
$ git bisect good v1.4.1
Then build from source and test at each bisect step:
$ ./configure --target-list=x86_64-softmmu && make
$ qemu -drive file=fat:floppy:...
If it fails:
$ git bisect bad
If it succeeds:
$ git bisect good
At the end of the process it will tell you which commit broke vvfat.

Triaging old bug tickets... Have you ever bisected the problem? Can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays?
