When running as a daemon, hddtemp uses over 4 MB RES memory, which isn't a lot, but by editing the hddtemp.db to only contain the three entries I need, the daemon uses less than 600 KB.

Since the drives to monitor are only specified at startup and can't be changed (ie start monitoring a new hotplugged drive), would it not make sense to "purge" all the unused db entries, freeing up the memory?

I'm not a programmer, so may be underestimating what's involved, but it looks like it would significantly reduce the ram usage when daemonized...
