[Gptfdisk-general] gdisk error

[Conrad G T Y. <cgt...@al...>]

I have a MacBook Pro, running OS X 10.6 with, of course, a GPT Disk. The OS X Disk Utility reports no problems with the drive, but when I try to repartition the drive, Disk Utility does not allow me to resize partitions. When I try to use the OS X command-line tool, I get the error, "Error: -9939: The partition cannot be resized." 

So I downloaded GPT fdisk and ran gdisk. Upon starting it, I get the messages: 



GPT fdisk (gdisk) version 0.8.1

Type device filename, or press <Enter> to exit: /dev/disk0
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.

Warning! One or more CRCs don't match. You should repair the disk!

Partition table scan:
  MBR: hybrid
  BSD: not present
  APM: not present
  GPT: damaged

Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.)
 1 - MBR
 2 - GPT
 3 - Create blank GPT

Your answer: 



And I'm not sure what the next best step here is. Any suggestions? Let me know if you would like more info.
