Tale of horror: lost de guid partition table. But... Found a solution

[Whalid]

Hi,

 

Last week I decided to play around with my partitions. I obviously did a very stupid thing and lost the GUID partition table. The information was there but diskutil list reported a FDISK_partition_scheme and not the GUID_partition_scheme.

 

I tried a lot of apps: Disk Warrior, Drive Genius... I was freaking out.

 

Then I found a piece of free software that solved the problem: TestDisk 6.

 

It recovered my lost GUID table and recognized my two HFS+ partitions. The only thing I had to do was to reinstall Chameleon EFI.

 

The only reason I am posting this: a had a really hard time looking for this solution, so if this happens to you... You can check this amazing life-saving software: http://www.macupdate.com/info.php/id/27683/testdisk

 

And thanks for the guy that created it. It saved my skin.

 

Cheers.

PS: Probably one of the gurus know how to solve this with the terminal... But hey, I am no guru

Thank you Whalid!!!

 

It took me some time to find out your post, having the same problem.

It is something that happens to me sometimes when I plug a disk in a RocketRaid controller.

The disk was initialized in Mac OS so recognised as a legacy disk by the controller's driver.

And then this driver changes the partition table or something and the volume becomes disk8s1 with no name and FDisk_partition_scheme.

This happened to me a few times in the past.

 

This piece of software rebuilt the partition scheme and it worked.

Great
