    /me too

    Thinkpad T23, with a ST980815A

    Ticks ever few seconds, but seems to mostly go away with
    hdparm -B255 /dev/sda1

    but I have an increasing seek error rate as well. I got the ST disk
    because thinkwiki suggested it.

    I suspect this problem killed the previous disk in this laptop.
