DVD/CD player does not function after replacing hard drive
I installed a greater capacity hard drive on a friends MacBook Pro.
The drive works perfectly, but the CD/DVD player will now recognize nothing--no CDs nor DVDs.
We don't live in the same country at the moment, so I can't reopen the case to look for the problem.
Any ideas as to the cause? I don't think I touched any other connectors, but perhaps I accidentally did.
