installed a new harddrive wdc blue 320 5400, verified in DU, .  I reinstalled 10.5,

can't see time machine. and now it is so slow that it  rainbow spins for 30 seconds after each click on any window, folder, button, anything.


I've updated,activity monitored, mackeepered. 

my last ditch is migration assistant (now on 30th hours).

to see if a retored orignal system and prefs will see the Time Machine backup, and get back from there.


it will work fine if booted to a usb drive with same system.


if I didn't know better, Disk Utility is lying to me and this is a bad hard drive or somehow incompatible with the dual core intels.


is applejack worth trying, onyx?


I may just hit it with a banana


thanks to anyone with the know how about this.

MacBook Pro, Mac OS X (10.5.8)

    Never install Mackeeper.


    Erase the disk, split into 2 partitions, put a clean OS on one from original install disks and clone your backed up OS onto the other.  Do not migrate anything onto the clean OS. Do not install any third party utilities on the clean OS except AppleJack and perhaps Onyx.

    Once you have an OS I think you should be able to use Onyx or SMART reporter to check the disk in addition to Disk Utility.


    Take a look at the Carbon Copy Cloner site - they used to have a page about why you should never use WD disks on a Mac. I have tried telling them that their problem is with WD enclosures and not the bare disks but you may still like to read their page.
