Permission to write files via SyncToy to router-attached USB drive RRS feed

  • Question

  • I'm trying to set up SyncToy to back up my photos to a USB drive which is attached to my router (a Netgear DGN3500). I have set it up but every time I try to sync I get the "Unknown error. Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))" error. I'm convinced this is something to do with write permissions to the network drive but I can manually read/write/change files. I've tried changing ownerships from ROUTER\\Root\ and running SyncToy as an administrator etc. but no joy thus far. Does anyone have any suggestions?

  • I have been having the same issue as well. It happened around the time I upgraded SyncToy about 6 months ago. I was using an older version, v1.4 I think, but was sick of that bug where it leaves empty folders on the right even after you delete everything on the left. So I upgraded to v2.1 because I heard it was supposed to resolve this problem. Also around the same time I had to blow away my USB drive connected to my LinkSys Cisco router and recreate the shares on it. All the security seems fine as I can manually copy files and folders over to the drive with no issues. However, now SyncToy only creates the folders on my USB (NAS) drive but fails to copy any files due to the same Access Denied HR Result error. I don't get it. Is it my upgrade to the newer SyncToy or my recreation of the shares that broke it, and if it truely was a security issue, which I don't believe it is, then why can I manually copy files and folders over with no issues????

    I've seen many different posts on this problem going back to 2007 or later and no concrete solutions from Microsoft!!!!

    Lucky for me I have a RAID mirror on my new PC so at least I have data redundancy there, but right now my USB drive connected to the router is useless unless I wan't to do a manual copy or robocopy or something. SyncToy used to be a pretty good solution for me and now it's just a piece of......

    Okay my rant is over now!
