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
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:      GUID_partition_scheme                        *2.7 Ti     disk1
  1:                  Apple_HFS                         128.0 Mi   disk1s1
  2:                  Apple_HFS                         2.7 Ti     disk1s2

sh-3.2#  gpt -r -vv show disk1
gpt show: disk1: mediasize=3000592981504; sectorsize=512; blocks=5860533167
gpt show: disk1: PMBR at sector 0
gpt show: disk1: Pri GPT at sector 1
gpt show: disk1: Sec GPT at sector 5860533166
