gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.8

Warning! Disk size is smaller than the main header indicates! Loading
secondary header from the last sector of the disk! You should use 'v' to
verify disk integrity, and perhaps options on the experts' menu to repair
the disk.
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.

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

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

****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.
****************************************************************************

Command (? for help): q


the same applies to all three hard disks (previously it only happened on /dev/sda while sdb & sdc seemed fine) 
On 10.04 all three drives function correctly and they are part of a fully working raid5 array, that contains an encrypted lvm filesystem.
               

on ubuntu 10.04:
