Hi everyone, I've looked around for an answer, but finding none I thought I'd ask the experts. I have a friend whose superdrive in their MacBook (first edition) went on the fritz. Rather than buying a new drive for approx. $150, I was wondering if the drive inside the external MacBook Air superdrive would do as a replacement? I figure cracking open the external superdrive is worth saving $50, but only if I can use that drive inside the MacBook. Thanks in advance for your help!
