I've probably found the solution, but I need testers... It seems that hdparm.conf isn't called anymore, because hdparm itself isn't called during boot. So what you can do is forget about hdparm.conf altogether, and alter the configuration file 20hdparm instead, which is located in /etc/apm/event.d
So: gksudo gedit /etc/apm/event.d/20hdparm In the text, you'll see the following text block: # The APMD_DRIVES setting specifies the drives to be changed. Set # this to an empty string to disable any changes. #APMD_DRIVES= Change the last line into APMD_DRIVES=/dev/sda (assuming that your hard drive is sda, which is the most common situation) At the end of the next text block, you'll see this: APMD_SPINDOWN=18 Change this into 254: APMD_SPINDOWN=254 Then you'll see a text block starting with: power_conserve () In that text block, you'll see this line: "${HDPARM}" -q -S "${APMD_SPINDOWN}" "${DRIVE}" || true Change the parameters for hdparm (delete -q -S and add -B instead): "${HDPARM}" -B "${APMD_SPINDOWN}" "${DRIVE}" || true Then you'll see a text block starting with: power_performance () There, in the hdparm line, delete -q -S as well, and put instead -B. It becomes: "${HDPARM}" -B 0 "${DRIVE}" || true Save and close the configuration file. Then reboot your computer. All should be well now. :-) Note: change 254 into 0, if you want to disable spindown entirely. As said, I need testers!
