Exception during preview: failed to detect changes RRS feed

  • Question

  • Hi,

    I used SyncToy for several years on my old laptop running XP without any trouble to back up to my university's common share drives over the university network. Now I've got a new HP EliteBook 8440p running Windows 7. I installed SyncToy 2.1, and sometimes it runs without trouble, but sometimes I start getting the error:  "Exception during preview: failed to detect changes". One oddity I've noticed is that SyncToy usually runs okay off a fresh login, but these errors tend to occur if I've been logged in for awhile and then want to run a backup. Since I'd rather not making logging off and back on part of my regular backup procedure, does anyone have any idea what's causing these errors and how to fix it?

  • Hi -

    What kind of files are you sync'ing? This error happens if we find directories are being moved around. It really should be a transient error ( since rarely are users constantly moving directories around). I am guessing ona  fresh login, there is some program that has not yet kicked in that is setting off this behavior - see if you can narrow it down to a particule program that you have running.
