*
* SdFat has a single 512 byte buffer for SD I/O so it must write the current
* data block to the SD, read the directory block from the SD, update the
* directory entry, write the directory block to the SD and read the data
* block back into the buffer.
*
* The SD flash memory controller is not designed for this many rewrites
* so performance may be reduced by more than a factor of 100.

* If ENDL_CALLS_FLUSH is zero, you must call flush and/or close to force
* all data to be written to the SD.
