Exception during preview: Failed to Detect Changes RRS feed

  • Question

  • New user here trying to make sense of everything.  I am trying to do an echo from a local hard drive to a network hard drive.  The amount of data is about 130gb.  The sync made it through 63gb+/- and then stopped.  Every time that I try to run the program again on the same folder pair, I get this error during the preview: "Exception during preview: Failed to Detect Changes".  Is this a known issue? Suggestions?  I am running 2.0 that I just downloaded yesterday.  The local machine is a W2k3 SBS server, and the network drive is on an XP machine with SP3.  Thanks.

  • Hi -

     

    Can you take a look at the log ( File->View Log) and copy-paste what is in there? If you could also turn on verbose logging before you send it to us. To change this – look at the SyncToy.config file in the SyncToy install folder and change the trace level from “Info” to “Verbose”. Re run the failing sync and let us know what you have in the log.

     

    Thanks

  • Here is the beginning and end of the verbose log.  I cut a large portion out of the middle to save space and keep my entire file structure off the web!  Let me know what you see.   Thanks.

  • I'm not sure if this was the cause of the problem or a result of the problem, but I wanted to follow up and let you know that the drive has failed.  It was about three years old, a WD 320gb.  I will re-try everything on a new drive and post here if I can duplicate the failure.
