Hi

I have been using gdisk for at least a year on Centos and F15/F16

Current Centos 6.2 server disk was probably partitioned using F15 gdisk
followed by a custom install of C6.0

Centos 6.2 gdisk is now installed on the server (maui, 256GB SSD)

[root at maui ~]# gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.1

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): p
Disk /dev/sda: 468862128 sectors, 223.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 238914FA-2437-4AD8-B803-5CA2860D9D93
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 468862094
Partitions will be aligned on 2048-sector boundaries
