Can anyone tell me why  OSX 10.4.11 spins up my hard drives every 20-30 min when I'm not doing anything that requires them..?  Then it powers them down after about 5min (you don't even have control over the time interval--just "Put the hard disk(s) to sleep when possible". How pathetic).


Just now I was sitting here at my desk reading, and suddenly.... brrmmmmm... both hard drives power up. Actually, I don't think it's even putting my startup drive to sleep, which of course would be a second major f#@k-up with regard to OSX behaviour.


But the *other* physical hard drive *definitely* should not be powering up. Thanks.

PowerMac, Mac OS X (10.4.11), G4; G5; Dual-Core iMac.

    You may be able to track it down with this software.



    I discovered a new toy.




    This command line program finds the same files as Spotlight indexes.


    Macintosh-HD -> Applications -> Utilities -> Terminal


    cd /Applcations/fslogger
    mac $ sudo ./fslogger
    fsevents device cloned (fd 5)
    fslogger ready
          ... clipped ...
    # Event
      type           = FSE_CONTENT_MODIFIED
      pid            = 233 (firefox-bin)
      # Details
        # type           len  data
        FSE_ARG_VNODE     85  path   = /Users/mac/Library/Application Support/Firefox/Profiles/Default User/sessionstore.js
        FSE_ARG_DEV        4  fsid   = 0xe00000c
        FSE_ARG_INO        4  ino    = 2444670
        FSE_ARG_MODE       4  mode   = -rw-r--r--  (0x0081a4, vnode type VREG)
        FSE_ARG_UID        4  uid    = 1000 (mac)
        FSE_ARG_GID        4  gid    = 20 (staff)
        FSE_ARG_DONE (0xb33f)







    double click on the dmg file.  This will create an icon on the desktop.  copy files to a new folder. Let's create this folder in the home folder.  name fs.


    You need to run it in the terminal.


    Macintosh-HD -> Applications -> Utilities -> Terminal


    # first you need to move the folder the fslogger program resides in.


    # in the example case


    cd ~/fs



    # or you can type cd then drag the folder to the terminal.  be sure to leave a space after the cd.  Press return after typing each command.


    # The sudo command will ask for your administration password. No characters will appear when typing your password. Press return when done typing. sudo stands for super user do. It's just like root. Be careful.


    sudo  ./fslogger

    Track it down..? Huh? How..? And I thought Mac OSX, Windows 95, and other "advanced" operating systems were supposed to do away with low-level screwing around like that?


    This problem is  an obscenity. My hard drives just spun up AGAIN--both of them--while i was watching a TV show across the room. This is frikin absurd. It's even worse than that. Apple garbage software is wearing out my hard drives much faster than they should be wearing out.


    Does anyone know how to fix this problem?? Can it not be fixed, i.e. OSX is just trash..? I have noticed that my hard drives NEVER spin up unnecessarily on my P4 running Windows XP. Thanks.

    This can be caused by lots of things.


    The first thing I would do is to disconnnect your machine from the internet & see if the problem persists.


    Look in Macintosh-HD -> Applications -> Utilities -> Activity Monitor

    see if you can see any odd apps running.




    You may want to run these "standard" fixes if the problem persists.


    1) Check the amount of free space on your harddrive.  You should have a several gigs free.


    2) You should run disk utility

         a) verify the disk

         b) update your permissions.


    3) Try a safe boot.

        Shutdown your machine.  Hold down the shift key.  Poweron.  Wait awhile Wait awhile while you harddrive

          is being checked.



    4) You may want to run applejack to clean up your machine.



    5) Run hardware diagnostics.  It's good for a sanity check.



    a lot more ways to fix your Mac.






    Take the Windows solution... erase hd & re-install all software.  ... just joking.



    PS. You want to work on the problem or complain?
