It seems like you can't set a modtime of 0 on a vfat partition. This may not be a valid thing to do, but it took me a long time to figure out it was a bad thing, as the error doesn't appear until the next time the error flag is checked:

>>> os.utime("testfile", (0.0,0.0))
>>> import time
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
WindowsError: [Error 87] The parameter is incorrect

Looks like a missing "goto done" in posix_utime(), posixmodule.c, line 2805. Could you test the following patch?

I'm afraid I don't have a Windows build environment handy, but a quick look at the function in question seems to indicate that is the problem. Thanks for the quick reply!
