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.

Thank you Neville.
I am still suspicious of my new Hard Drive's efficacy. verifies, but will not unmount after erase, and now the clean OS X install is pushing 2 hours.
this seems like pre drive failure behavior.
any last ditch ideas.

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.

thank you Neville that was alot of help.
I am faced with believing the few discussions concerning slow replacement drives, that claim, that the new WD drives have firmware issues with the os x 10.5 2009 macbook pro's as well as any drive with a speed greater that 5400. all my utilies onyx & DU, say my drive is functioning.
however every operation that involves the new drive (whether it was the boot drive or not) takes 30 -60 times the speed I am used to.
I am now going to search for a confirmed compatible replacement drive.
thanks for upgrading my thinking on drive set ups, that will hold me in good stead for years, and I appreciate that very much
