As I mentioned, someone suggested off-list that I run sdparm in a cron job like this: * * * * * /usr/bin/sdparm /dev/sdd > /dev/null That could very well be overkill, but it seems like a very light-weight process. In any case, my USB drive has been up without a single disconnect for several days now. Looks like the person was right: The drive was going to sleep on me. I hope this information helps someone else. Thanks all, Reid
