How hide EFI Partition?
Hi guys!
I was trying some things and I execute the comand below: Code:
diskutil eraseVolume "HFS+" "EFI" /dev/disk0s1 There is some way to hide EFI Partition again? Maybe some obscure diskutil command? Please help! |

UnMount EFi:
umount /Volumes/EFI (If this fails, do umount -f /Volumes/EFI) rm -rf /Volumes/EFI |

Thank you this works, but when I restart the computer the EFI partition appears again on the desktop.

I think you're EFI partition isn't recognized any more by Mac OSX itself...
If you use a program like iPartition it will be recognized as EFI I think... But the OS itsself doesn't anymore.. I once did have that problem also... But didn't found a real solution also....

The problem is almost certainly that the partition type code for the partition has been changed. You can change it back with any of several utilities. I'm not very familiar with the command-line diskutil program, so I can't help you there. If it's an MBR disk, you could use fdisk to do the job. Unfortunately, I'm not very familiar with the OS X version of fdisk, but with the Linux version of the program, you'd launch fdisk, then use 'p' to view the partitions and identify the one you want to change, then use the 't' command to change the type code. Assuming this is an EFI System partition, the appropriate type code is 0xEF (you usually omit the "0x" part in disk utilities). You'd then type 'w' to write your changes to disk.
If it's a GPT disk, the appropriate code is C12A7328-F81F-11D2-BA4B-00A0C93EC93B, but most utilities (understandably) don't accept GUID codes like that directly. You could use my GPT fdisk to do the trick. It works much like Linux fdisk; launch the program, then use 'p' to view your partitions, then use 't' to change the type code. In GPT fdisk, that would be EF00. When finished, use 'w' to write your changes back to disk. |

It´s a GPT disk with 2 HFS+ partition + EFI hidden partition, this always happen if I format the EFI partition, I tried to recover from a Norton Ghost image that I had but did not work too. I will try your program later when I go home. |

Yep, it's because after formatting, the partition gets wrong name and type code.
Use a small utility, called "gdisk" (GPT Fdisk), install it and run it from the terminal. - the "p" switch will print to you various details - the "v" switch will verify the disk and print out errors, if found You will see that neither the name of the EFI-partition is "EFI", nor the type code is "ef00", which is the proper one for a EFI System Partition. And for the correction, you will need two switches : - "c" for changing the partitions name - "t" for changing the type code to "ef00" - "w" for writing the changes to the disk Unmount the partition, restart and you'll not see it mounted anymore Hope this will help you out. Greetings P.S. It seems that i have overlooked a user's comment, which already helped |
