SanDisk X400 1TB SSD won't boot internally - is it too big?!
My mid-2009 MacBook Pro was getting slow with its 750 GB hard disk, so I decided to upgrade to a San Disk X400 1TB SSD. I formatted the disk using a Sata to USB cable, clean installed Mavericks and used migration assistant to transfer my files. I can boot the laptop from the drive just fine using the USB cable. However, when I connect the drive internally, it won't boot. If I then connect the old 750 GB drive to the USB cable and boot it from the old drive, the new drive shows up on the desktop, but I can't open it or otherwise do anything with it. SanDisk thinks my computer may not accept a drive that size (that 1TB is too big!) but I don't think that's right. Can anyone help me out with this?
Is this a good question?
