3TB GPT HFs partition recovery error

#1 Post by yassersh2001 » 22 Mar 2012, 21:57

mac drive 9 corrupt my external WD 3 tb GPT hfs partition green HD
my partition map are
p- efi start 40 end 409600
p-HFS+ start 409640 end 580270983
when i try to manual add partition with start end sectors methods for efi its done with no error
when i add HFS+partition and wrote the end sector its changed from 580270983 >15600563 with total space 749GB only
i try to use GPT partition map from another hd with the same partition map but same result
i noticed that pdisk and test disk only read max 2TB by sectors length but with search and deep search i can write more than 2TB sector length but with wrong map with manual modify only can add 2tb

Do you have an older Power PC or an Intel MAC?
Intel Mac uses EFI GPT and you need not pdisk.
You can write your partition directly in TestDisk.
