    ive been trying to get rid of this stupid whirring/clicking sound that happens for 6-10 seconds every 10 seconds or so... ive since learnt that its aggressive power saving mode in my HDD (that Linux programmers refuse to sort out like windows programmers do) - trying to fix it i used the hdparm code setting - does this make permanent changes in the hard-drive that would reflect in windows if i boot back into windows? - i tried the 255 and 254 code and none of which worked but after coming back into windows there seems to be random clicks more often than before.. i dunno if its just me worrying that ive broke my hard-drive by trying these codes and thinking it is or wot

    so are these changes permanent or do they reset at boot?

    Hi paulb100,

    Have you tried booting into the BIOS to determine if you can disable PM?

    Also, have you checked the man pages for (hdparm, sdparm) after using hdparm or sdparm to determine if a reboot may be required?

    Also, what kind of hard drive do you have (Western Digital, SeaGate,...) and is it PATA or SATA?
