When reading/writing block devices, Cygwin emulates Linux, providing a byte-exact file position, albeit the underlying device drivers don't. Unfortunately this only worked correctly for reading. The raw_write method failed to revalidate the buffer after the read-modify-write cycle in case len is not a multiple of the sector length. This in turn resulted in lseek reporting a wrong file pointer. Also, fix a condition for invalidating the buffer after writing from a remaining read buffer.
