This is most likely a test to see if HWInfo and the final firmware can be written or not. PREWRITE creates and signs HWInfo just like PREPARE does, though PREWRITE seems to have extra steps such as backing up/restoring logs during formatting. PREWRITE writes the following log entry which is not found in any DSi logs. This means PREWRITE is likely not used.
0,PWRITE,OK,1.3, , , ,S/N=,
This is the PREWRITE function list:
