Perhaps you should try reinstalling the MTP driver, see if that fixes your problem, if not go back to MSC.
I haven't ever had any issues creating folder directories on my S-545 (and I've configured as as Mass Storage Device), but then again I just prefer to create mixed folders rather than Artist>Album>Song sub-directories.
EDIT: I just tested out creating 150 folders in the music directory and had no issues.
