Hi all, I installed a new Hitachi 500GB travelstar drive and restored it with all my data. Everything was working fine until I updated the EFI firmware to 1.7. After doing this, my MacBook pro won't even recognize the drive in disk utility. I even tried the old drive, and that didn't show up either. However, when I plugged the drive into a sata to USB connector, it would boot fine. Is there any way to fix this? * I have a unibody MacBook pro (5,5) * Thanks for any help, this whole process has been a nightmare!
