Indeed. Linux uses (extensive) buffering. Your write command may return but the data be still in memory instead of written on the drive. If you disconnect it right away, besides a corrupted file system you may find that your files are incomplete or missing. So, with FAT FS issue a sync and wait for it to return or, much better, unmount (which forces a flush of the associated write buffers). Regarding the mount read-only, the kernel may decide to do so if the FS has errors. It should resume mounting it RW once the errors are fixed.
