another idea: put the install dvd in the optical drive, then hold down the C key during bootup. this will force a boot into the install dvd. wait for the optical drive to spin down (about 2 minutes then hit command-F5 and voiceover will start. after this, go to the utilities menu item, start disk utility, highlight the HD and go into the first aid screen. choose verify disk and let it check the drive. if something shows up in the pain (table) above that, then hit repair disk.
at this point, you might make you already have a backup of the disk. this way, if anything is seriously wrong with the disk, you will have a recent copy to work from while you order a replacement HD. I have had to do this more than a few times since OS X tiger. -Eric On Jun 19, 2011, at 4:35 PM, Esther wrote: > Hi, > > Ezzie, here's yet another suggestion: it's possible that you have a bad > sector on your hard drive that prevents your Mac from completing the boot up. > If so, it's still possible to boot your Mac from an alternate drive, and > also access your original disk (any parts that are not damaged), if you've > created bootable clones with either Carbon Copy Cloner or SuperDuper! as part > of your backup strategy. > > To boot from a backup that's been created as a bootable clone, connect the > drive, then hold down the Option key while you turn on your computer to start > booting.
