This thing is starting to really frustrate me now. So I wan to copy some pdf files and movies to the Nexus 10 32gb. Sometimes it works fine, then sometimes I try to copy stuff and it will get part of the way through then tell me the device has become disconnected though I can still browse the directories of it. I transferred gigs of files to it the past few days and ran into this a couple times, but now I'm having all kinds of issues, mainly with large collections of files, like a bunch of videos or comics. I just managed to get a 1.25 GB collection of files transferred by doing files individually but even when trying to transfer files inside the device I'm running into errors about the device has stopped responding or has been disconnected. How can I get that error when I'm moving files from one folder to another on the device's drive?
