What do I do if I lost my restore DVDs and have a corrupted HD in my Macbook Pro 2010? I have a Macbook Pro 2010 (Core2Duo), and I lost my original software and OS restore DVD. The one that came with the laptop. Now my HD volume is corrupted (many programs quit randomly now -- like iTunes, XCode, etc). What can I do? Can I just go buy an OS X Lion DVD, reformat my HD, and do a clean install? Or do I somehow have to get the original DVD that came with the Macbook Pro and start from there? Please help. Thank you.
There is no Lion DVD on sale, however, Apple sells Lion USB Key, that you can use to reinstall Lion on a new hard drive.

What you won't have, though, is iPhoto, iWeb, iDVD (I probably forgot some) that come when you buy a Mac.

But if you bought them on the Mac App Store, you'll be able to reinstall them at no charge.
