----- Original Message ----- | As you know I've been testing centos on an old mac pro. I have 1 | disk left | of 4 that I'm testing on. I had a 3TB disk and stuck it in and | couldn't | get centos to boot off of it. It would install, but not boot. I | then got | "old" disk 4 installed with it. Any idea why the 3TB disk doesn't | work? I | pulled out an os x 10.6.3 and that would install and boot. I resized | the | disk in osx and reinstalled centos, but centos still won't boot off | the 3TB | disk. | | Thanks, | | -wes To boot off of a 3TB disk you require a (U)EFI capable machine which supports GPT partitions. There is no way to boot a disk that is 3TB in size using a BIOS based machine. -- James A.
