I have a nexus 7 and have all the right stuff to get the sd card work as far as read/write, but when I hook up a usb disk drive I only get read access. I am using stickmount and paragon ntfs. I have up graded to 4.2.2 and all else works fine. I did notice that paragon says it does not work yet with 4.2.2, Is there any work around to get write acess to the dard drive?
