Compiling: ---------- run: make OR cc wdsaver.c -o wdsaver Usage: ------ Run: ./wdsaver -h Testing: (as root) -------- (assuming defaults parameters being used) 1) Select timeout say 40 seconds 2) Do a test (non-live mode) run: ./wdsaver -t 40 -v 3) Check the output i.e. functioning of program 4) Once satisfied, put in live mode and test again: ./wdsaver -t 40 -v -l 5) Check the output i.e. functioning of program TIP: ---- For 'random read' method (see usage), if your most active partition on the drive is /dev/sda3 (say /home or just /) then it would be nice idea to specify it as a device (-d option) to read from. That should reduce head movement away from the active partition. Installing: (as root) ----------- 1) Once satisfied with testing, run make install OR copy the file to /usr/bin cp -i ./wdsaver /usr/bin; chmod 700 /usr/bin/wdsaver 2) Put the following in rc.local of your system startup: /usr/bin/wdsaver -t 40 -l -b Enjoy, the safety of your drive and drive safely!
