New 2TB HD not recognized - can't format

So I followed the replace HD instructions from ifixit - went smoothly. Replaced my original 320 GB with a 2 TB WD.

When I try to format the HD, it will not get past the Apple icon - so I can't get int the Disc Utility. I've tried holding down the Control.. Option and C buttons. It will show me the CD option (without the HD of course) but when I click on the arrow - it goes back to the Apple Icon and the spinning wheel of death :)

Any help or tricks would be SOOOO Appreciated!

Thanks in advance for your help!

Can you tell us the brand, model & size of the 2TB HD your trying to put in. Did you try using an external case or adaptor to house the new drive in before opening your system to prep it?


Thanks Dan - The HD is a WD2002FAEX. I opened the imac, replaced the HD and loaded the disc - held C - just a apple with spinning wheel.. I read as part of the HD swap, I could boot from my Mac OS X Snow Leopard disc tility.. Sadly, I have not been successful..

Mike - You may need to get a different HD if this does not work.

This drive is a SATA III (6Gb/s) and your system only has a SATA II (3Gb/s) HD interface.

Here is the Black Series drive jumper settings: Jumpers. You'll need to place a jumper to lower the I/O speed to 3Gb/s for this HD to work. If the drive doesn't work after adding the jumper you'll need to look for a different HD.

Could it be that the iMac won't take a 2 TB dive by chance?


No, It should work. Mac OS-X supports large HD's like this without any problems.
