    My computer is doing a disk access about every 30 seconds or so. This prevents it from putting the hard drives to spin down and prevents the Mac from going to sleep. A bit of a problem when running on battery unplugged from the AC power.

    PowerBook G4 15" AL 1.67GHz 2GBRAM
    (PowerBook5,8 = PowerPC G4 (1.5))
    MacOSX10.4.11 all up to date

    I have stripped down all extras such as MenuMeters, Tablet, DejaVu, etc.
    I have quite out of all applications so that just the Finder is running.
    I have sharing turned off (personal file, printer, fax, etc).

    Listening I hear the hard drive click approximately every 30 seconds.

    Opening and watching Activity Monitor I can't spot the culprit.
    I don't see anything to alert me in Console.

    Any suggestions on pinpointing what task is doing the disk activity that is blocking hard drive spin down and sleep?

    Many thanks,

    -Walter

    If you have XCode 3 or 4 installed, then you can use Instruments to look at disk access.
