Hard drive replacement recognition
Just replaced the HDD with a known working one. It is not being recognized.
When I start up from a dock unit has no problems, but does not show the newly installed drive. Unit works fine from the external dock (drive).
I have apple service manual and have viewed you replacement video. From what I can tell the drive is properly installed and everything plugged in properly. So what am I missing, or where should I be looking?
Not my first rodeo… and as you know these units are a bear!
