Yotam, one possible culprit from your ps aux list is
root 1909 0.0 0.0 1816 672 ? S 17:38 0:00 /usr/sbin/hddtemp -d -l 127.0.0.1 -p 7634 -s | /dev/sg0 /dev/sda But this should really only read from the device, not write to it. I didn't see anything obvious which would open /dev/sda in write mode. Do you still have this problem with Ubuntu 10.04.1? If so, can you please give me the output of sudo fuser -v /dev/sda while this is happening?
