    This Mac mini keeps loosing it's hard drive.
    I boot up into normal mode. Grey screen freeze or login then freeze.
    I boot into safe mode, blue screen freeze or login freeze.
    I boot into single user mode, fsck works fine.
    Sometimes I reboot and the hard drive isn't there.
    Sometimes I run diskutility 'repair disk' and it quits halfway through and the drive stays unmounted.
    Reinstalling SL fails a few minutes in.
    Running disk utility off the disk sometimes works and sometimes doesn't.
    Often the drive disappears from the disk utility in the boot disc.
    Then the only way to get it back is to reboot with pram reset.

    This is just a bunch of craziness, the drive was working fine a few minutes before.

    I don't know, but it sounds like a failing drive to me, but its curious to me too.
