I recently started experiencing the problem where Transmission directories spontaneously disappear (the folder where both the torrent description file and the actual file itself are stored: to stay organized, I put each running torrent in its own folder within a 'TRANSMISSION_EXTERNAL' folder (to denote it lives on the external 1TB USB HD). I realize this isn't the latest version of Transmission, but the CPU limits me to a 32-bit non-PAE OS and this is what got installed with it. Thus, this netbook is the one I leave on 24/7 and it routinely hosts a few hundred torrents at a time, including 'longshots' some will probably never finish, but once in a while one does.

a bigger/faster/hungrier PC doesn't DL/UL torrents any better. This PC was rescued from a recycling bin, an external 1TB USB HD was added and the minimalist CrunchBang Linux distro installed (now BusenLabs Linux: ) and this little netbook has been running Transmission 2.52 (23304) great. My main torrent PC is an ancient Dell Inspirion netbook w/a lowly Pentium M CPU and less than a half GB of RAM. I've been using Transmission on a few different Linux PCs/distros for a couple years and generally love it. I was unable to find a solution, other than removing Transmission completely and re-installing it, which doesn't really explain the problem, or give confidence that it's a meaningful fix. I did search for prior posts about the problem I'm experiencing.
