[QUOTE="dizzyland, post: 1810744, member: 401540"] I went ahead and reformatted the external standard HDD again and made sure the GUID partition was selected and it still didn't work. Then I verified and repaired the disk and it worked perfectly. After that I installed mountain lion on the external drive and updated it to high seirra which gave me the firmware update I needed in order to get the board to see my internal ssd. It's now running great and all is well. Thanks for the help! [/QUOTE]
