I have tried setting up my pi so it can download torrents to a USB drive. However, the transmission web interface is giving me all sorts of errors like: "Not enough space", "incorrect file permissions" and other errors. Sometimes, it only downloads to the pi's SD card, not the USB drive. I have edited /etc/fstab so my drive mounts on start-up, but this dosen't work all the time and I can't change or take ownership of /media as the "pi" user because the root user has permissions to that.
512 mb Model B Rev 2, 16Gb class 6 SD card. Raspbian 2013-05-25.
