Well, it seems this forum may be abandoned (nothing new in 2 years?), but I will post here anyways and see what happens.

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.
