I am trying to copy the contents of my Bitcasa (formerly) infinite cloud drive to an external hard drive.

I had manually copied a number of the folders (painfully) using the windows interface, but some files were omitted.

FreeFileSync is able to scan the infinite drive and the external hard drive and detect which additional files need to be copied over.

When I go to start the process, I get this error:

Error Code 31: A device attached to the system is not functioning. (CopyFileEx)

Any help greatly appreciated.
