    yo. i checked the smart readouts for my hard drive. it is a month or so old and already has 6839 load/unload cycles. good god. does everyone else get these kinds of values? i downloaded the power booster utility from hitachi and set it to maximum performance.

    i hope this decreases the ridiculous amount of load/unload cycles. has anyone else found a fix for this, or do most consider it not worth toying around with?

    hehe... i have seen 300,000 as the number of load/unload cycles the hitachi mobile drives can take. at 7000/per month, i'm not too excited about the projected lifetime of the drive! although, i am not sure if the jury is in yet as to smart values and hard drive life.

    seems like the hitachi drives park/unpark the hard drive a whole lot. probably set to kill the drive right... about... when three years is up ;)

    lol. 7000/month X 36 months = 252,000 load/unload cycles.

    sure, parking/unparking the drive head might be good for battery life, and reduce the risk of data corruption due to jostling, but 7000 freaking load/unload cycles a month? zoinks!

    it looks like it doesn't make a difference whether i could set the value for the advanced power management or not. according to hitachi;

    BIOS can change these values on the next power
    on cycle or reset.

    there goes that idea. it would be nice if i could control this in bios, but i haven't found that setting. hello, lenovo?

    ah! got power booster software working. i suppose i will see in another month or so if it made a difference. ;)

    edit: every time i restart/turn on, the hard drive is reset, so i am changing it back to max performance each time. hooray for hibernate. i am not sure, but i think the aggressive battery life setting for these hard drives might be good for battery life, bad for hard drive longevity. i'm sure some linux users can relate to this problem. it would be nice if we could control this in the bios. -ahem- lenovo!?
