I've replaced the DVD drive in 2010 15" MBP with a 750 HDD. I can hear the drive spinning, but how do I get the OS to recognize the new drive?
If installed correctly, should be automatic I believe. Coincidentally enough I did the same in an early 2011 about 3 hours ago and was up and running.
To clarify, nothing shows up in Finder either? What about Disk Utility?
No, unfortunately no appearance in either finder or the utility. I'm thinking it must be a bad drive. I can hear it spinning though.
