Why won't my computer recognize my original harddrive in dual HDD?
I have made my Macbook pro 2009 model a dualharddrive, by replacing the optical drive.
But for some reason the harddrive (even if I switch them) placed in the original slot won't show up. Its neither showing when I hold the option button on start up or in disk utility. (both have OSX on them, so they should show at startup).
I've tried replacing the hdd cable and tried switching the drive. It is not the drive nor the cable.
Any ideas what it could be?
Is this a good question?
