How do I wipe my hard drive?
I recently bought an external hard drive to transfer all of my files off my Macbook Pro so I can wipe it clean.
I successfully backed up my computer with the help of Time Machine.
My questions is: How do I wipe my hard drive? Step by step instructions would be greatly appreciated!
**I don't believe I have access to any disks that came with the computer when I purchased it (6 years ago). Is there anyway around not having the disks? Once my hard drive is clean can I update my computer to the new operating system? Is that free (dumb question?)?
***My computer knowledge base is quite minimal at best.
MacBook Pro, Mac OS X (10.6.8)
