I plugged a 250gb powered external HD, that was on a Win 7 machine, into the OTG for my T310.
It recognized it, but came up as empty, and unsupported file system.
Since there was already stuff on it, I didn't want to format it or anything to see if
I could get further with it.
But it did recognize it as a drive. I don't know why it couldn't see anything on it though.
Im gonna see if I can get a 64gb thumbdrive and try that. I know the 32gb works.
