A 2KB file is about the right size for the file header ( 1024 bytes ) and the metadata only. 2KB would probably have little or no real data in there at all. I've had this once or twice and the usual reasons were....

  • I'd filled the SD card and there was only enough room to write the file header.
  • The ODBII cable connection was interrupted mid log, causing the V2 to abort writing data.
  • The SD card was removed from the V2 before canceling the logging operation.
  • The SD card suffered a connection loss during the logging process.


There have been one or 2 rare occasions where I have corrupted a file like this by turning off the ignition before stopping a log. But that was a couple of firmware revisions back and I haven't been able to replicate that. So I think it may have been an SD card issue. I've since swapped from using a 2GB card to a 32MB card and found it to be more stable. Perhaps the use of bigger cards may take up more resources and cause an issue?
