First of all, thanks for doing these videos! You are the only one who tells us about USB host on devices and its much appreciated! I watched your video before buying my Note 2, and I kind of hope and prayed about the 1TB thing.
I have been at it on and off for 2 days trying to get the Note 2 (stock 4.1.1 rom) to recognize any of my 1TB HDs. I've got a USB 2.0 and USB 3.0 to try. I've got 3 Y cables and 2 powered hubs. One is a 4 port and one is a 7 port. Nothing seems to work. I've tried formatting FAT32 and tried Paragon NTFS. I even did something dangerous, I tried plugging in one of my Y cables into a 2.1amp USB mains adapter. Thankfully it did no damage, unfortunately it didn't work either.
I was wondering if you have any ideas or tips I could try that I might not have done already. I have, till after Christmas, a SG3 (not mine) that the Y cable and 1TB USB2.0 HD works on with Paragon NTFS (USb 3.0 does not work). Its baffling me why the 1TB won't work on the Note 2. 500GBs work fine (as you demonstrated on your video) but the 1TB will not work and I feel like it should be.
