CoreView File Recovery

CoreView File Recovery

If the DVR Express Core loses power during a recording, the file being recorded is "incomplete" and must be repaired in order to access it.  As well, if the Core is disconnected from the Control PC during recording and the DVR fills up the SSDs, recording will stop but the file is still not "complete" until a procedure is completed by CoreView.  

File recovery is quite quick; at the worst it’s on the order of a few minutes.  Here’s some case examples of when recovery may be needed:

Case 1: Power loss

  • Video recording stops when power is lost
  • When user re-applies power and CoreView is launched again, the user is prompted with a message saying “an incomplete recording has been found”.  Options are to Ignore, Delete or Repair the incomplete recording.  ‘Delete’ deletes, ‘Repair’ repairs, and Ignore allows user to review other recordings while ignoring the incomplete one, then later go to Storage Manager to repair the file.
  • The incomplete file takes up all available free space on the SSDs.  Until the incomplete file is repaired or deleted, or other recordings are deleted to free up space, no new recordings may be created.

Case 2: eSATA disconnect with reconnect before recording fills up SSDs

  • CoreView should re-detect the DVR and, though many warnings may appear in the log, operation should continue normally

Case 3: eSATA disconenct with reconnect after recording filled up the SSDs and automatically stopped

  • CoreView should re-detect the DVR and will automatically repair it (user gets log message that “recording has stopped” once this happens).

Case 4: eSATA disconnect then later power loss

  • DVR keeps recording until point of power loss, unless SSDs fill up.  User must re-connect eSATA then follow steps from Case 1.
