I put in two Samsung 840s at 256GB and RAID-ed them together and installed Windows 8.
I'm having trouble using gdisk to get ready to install Linux.
gdisk sees the array, /dev/sda0, as a whole drive, but the size value comes from the individual disk as opposed to the individual disks combined. The graphic user interface, gparted, throws out a bunch of errors.
I'm using Intel RST to do a RAID0.
How do I fix my disk to make gdisk work?
root@ubuntu:~# 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): v
Caution: The CRC for the backup partition table is invalid. This table may be corrupt. This program will automatically create a new backup partition table when you save your partitions.
Problem: The secondary header's self-pointer indicates that it doesn't reside at the end of the disk. If you've added a disk to a RAID array, use the 'e' option on the experts' menu to adjust the secondary header's and partition table's locations.
Problem: Disk is too small to hold all the data! (Disk size is 488397168 sectors, needs to be 976783360 sectors.) The 'e' option on the experts' menu may fix this problem.
Problem: GPT claims the disk is larger than it is! (Claimed last usable sector is 976783326, but backup header is at 976783359 and disk size is 488397168 sectors. The 'e' option on the experts' menu will probably fix this problem
Problem: partition 2 is too big for the disk.
Identified 5 problems!
Command (? for help):
Using 'e' in the expert menu doesn't fix the problem. Also the problem persists in gdisk 0.8.10
