Mac can't read GPT ?
Hi,
I'm fixing my fiends USB drive.
AFIK it was inserted into Windows, and partition were corrupted.
I did manage to fix GUID headers with gpt_surgeon.pym but then mac did got messy, and sth happend,
Now Disk Utility Tool show's only 2 partitions out of three...
I do have a copy of my gpt header, and i did restore it with gdisk, but eventhough I can see partitons, mac (diskutil) still sees only 2 of them
HOW MAC INITIALIZE DISK, WHY CAN'T IT READS GPT
sh-3.2# diskutil list /dev/disk1
/dev/disk1
