Basically, my macbook internal HD is stating that it needs repair. System is running super sluggish and getting the beachball a lot. On a friends MBP, exact same symptoms, I repaired the HD from the OS X cd in Disk utility, and it was greatly improved... Having said that, my MB drive is dead, so I can't boot from the CD. I found how to boot from an external drive, but how do I make a copy of my OS X CD? I have a windows 7 computer also, are there any utilities there that will be able to do it? Like, can I rip it somehow, put it on my iPod, then make a DMG in OS X to put on the external? Any help would be greatly appreciated.
