Why will only the original hdd work in my MacBook?
I have a late 2008 aluminum MacBook. The hard drive was failing so I bought a replacement and cloned the original.
Before I put it in I made sure it was working with a SATA to USB adapter. However, when I put it in it gave me the flashing question mark, so I made sure again that it worked externally and it did.
Here is where it gets funky, I think oh crap I broke the cable but before I go a buy a new one I'll put the original hard drive in and it boots up fine. So the new hard drive works fine but won't read internally. And I know its not the Mac because as I said the original still works in it. (On phone so I apologize for grammar)
Ist dies eine gute Frage?
Be careful here! Your system was designed to support a SATA II (3.0 Gb/s) drive. Newer drives are mostly SATA III (6.0 Gb/s) only (fixed speed)! Some drives offer support of the slower SATA specs we call these Auto Sense as they match the systems I/O speed. As an example this drive: Samsung 860 EVO SSD is one of the few which supports SATA II (3.0 Gb/s) systems.
