Hard drive changed but not seen on the disk utility
I bought a new hard drive for my macbook pro 13" unibody 2009, i bought a Western Digital Scorpio Black 750Go, to change my poor old 160Go.
I've installed it correctly on the macbook pro, and when i put an install cd, it's not seen by the utility disk.
The only thing it sees is the optical drive, not the hard drive.
When i put the WD Drive on an another mac (or pc) as an external drive, it works.
Does this disk not compatible with my mac? or is it something else?
Is this a good question?
