Did you notice that 'restart' makes a stop and a start?
Then you settings are there again. Fine.


When you do a 'stop', your settings will most likely be gone. Try to do a
stop, not a restart. Then check your parameters.

Ok, here's some output. ;)



xerxes root # hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  1 (on)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 14946/255/63, sectors = 240121728, start = 0

             [note: i'm assuming this next bit is what happens during a
reboot - i.e. the service is stopped, then restarted next bootup]

xerxes root # /etc/init.d/hdparm restart
 * WARNING:  you are stopping a boot service.

xerxes root # hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  1 (on)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 14946/255/63, sectors = 240121728, start = 0

So it appears that hdparm isn't what is resetting the keepsettings flag, so
what is? :oS
