I have installed a second drive into my MCP. However the drive does not appear in the Disk Utility. I do see two Serial-ATA devices in the System Preferences. One is the main HD. The other does not display a drive like the main one does. Does this need a special driver install? Or what else may cause this? Thank you in advance!
Todd - I think your drive is too fast for the systems SATA port. You state the drive is SATA III (6.0 Gb/s), but your system can only handle SATA II (3.0 Gb/s). See if it offers a jumper to slow it down otherwise you’ll need a different drive.
First run this update: http://support.apple.com/kb/HT1237?viewl… You may run into more issues with the hard drive cable. If you are running 10.8 or better, put the old HD into the optical bay position and see if it will boot. Then put the new drive in the hard drive bay. Start up holding down the “R” key and see if you can run Disk Utilities to format the new drive. Let me know your results as I may have other suggestions.
I figured out my problem. The cable was torn. I ordered a new on, and it works great. - I also put the drive in an external case and plugged it into my Mac Pro. It came up in disk utility, so I formatted it. After getting the replacement cable, I put it into my laptop and it appeared fine. I did have to re partition it to get rid of the permission issue. But it is running fine now. I guess the system only uses 3/gb of the speed even though it is 6/gb. shurgs -Thanks for the replies!
