I have a message that is continually popping up saying that "Mac OS X can't repair the disc Home folder" It also says that I can still open or copy files on the disc but I cannot save changes to files on the disc. I need to backup and reformat it as soon as possible. I have purchased and downloaded Clean My Mac and ran it thru several times but I still get the message. How do I Back up this disc and reformat it?

    At this point you can't backup the disc because it's unverified and/or unverifiable. At best, you should be able to copy your files over manually to an external drive to save them, and then do a clean reinstall from your install disk. Clean My Mac isn't going to repair a disk.

    No idea why it happened. Any external USB or Firewire drive would do. I can't guess about the Windows side of things, sorry, because I don't have that on my Mac. But I do have the same iMac as you. To copy just your files, right click on each one, and make a Duplicate, then drag the duplicate over to the external drive. You could try making a bootable clone onto the external drive, but given that your disk is unverifiable, I'm not sure if that will work. If you don't have a lot of data, it makes sense just to manually move your files over to the external drive, then reinstall OSX from your install disk, and then move your files back. But you will lose any applications you added on top of what came with your install disk. You'll essentially be going back to the way your computer was right out of the box. The only way to save them would be with a bootable clone. Have you performed the Apple Hardware test to make sure it's a not a hardware issue. Insert your install disk 1, power off, then start up again holding down the D, and you'll be taken to the hardware test.

    No, your programs should be safe. Follow these instructions to use Disk Utility to repair your disk:
