Bug #3237: msdosfs: can't properly read files longer than couple of kilobytes
http://bugs.dragonflybsd.org/issues/3237#change-13954

* Author: piecuch
* Status: New
* Priority: Normal
* Assignee: 
* Category: Other
* Target version: master
----------------------------------------
Reading a file from msdosfs reports valid data within the first couple of kilobytes, everything after that is only NULL bytes (or it might be some data from a different sector which is currently zeroed).

I have tested this on the following configurations:
write on Linux - corrupted data on dfly, correct data on Linux
write on dfly - corrupted data on dfly, correct data on Linux

I am running latest version from master.

I will see if this bug can be reproduced on freebsd and try to fix that/port stuff from freebsd. Hints welcome.
