There's a good reason that DOS file systems get mounted read-only.
The file system code *was* buggy, and a write to an MS-DOS file system
could cause file system corruption.  I don't know if it's still the
case--maybe somebody else can comment--but you should know the
potential risks of writing to DOS file systems.
