USB Hard Drive Locks up Windows Explorer

Thread needs solution

A month ago, my Dell E6410 laptop was re-imaged. I re-installed Acronis 2013 and immediately began having stability problems when I plugged in my USB hard drive. At first I thought it was the drive, so I swapped devices. Same problem. Tried the drive on another laptop. No problem. Explorer would lock up so severely, that power cycling was the only way I could recover the computer.

I'm running Windows 7 Enterprise N SP1.

Finally, I went down a path recommended by Microsoft and disabled all non-MS processes. That seemed to work. Suspicious it might be Acronis Non-Stop Back-up related, I enabled all the processes but that one, and everything seems okay. I've read in these forums about other process issues affecting Explorer.

Am I on the right track, or am I missing something? I recall having other "stability" issues with non-stop back-up, so I stopped using it some time ago. Everything works perfectly when backing up to my NAS drive.

Thanks.

I thought the NSB stability problems that appeared in 2012 had been solved. If you weren't getting the problem before reinstallation something must have changed software wise.

Have you tried the following-

1. Repair install of 2013.

2. Check that your firewall or AV software isn't trying to block NSB.

3. As you are running an Enterprise version is the image a SOE from your company? Perhaps a new image has locked something down or has newer drivers that the original didn't ahve.

I'm not sure if downloading a different copy of SNAPAPI.sys would solve the problem in your case especially if you are not having any problems making images or file backups.
