[ONE Q&A, Help & Troubleshooting] DSwissK:
Some terminal output which could help :

root@swiss-ThinkPad-T400s:~# gdisk -l /dev/sdb
GPT fdisk (gdisk) version 0.8.8

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: 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.

And I get an I/O error when I try to push the system.img :

root@swiss-ThinkPad-T400s:~# dd if=/home/swiss/Bureau/system.img of=/dev/sdb14
dd: écriture vers «/dev/sdb14»: Erreur d'entrée/sortie

Boot.img cache.img and recovery.img didn't send that error though.

Some more info...

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: main GPT header's backup LBA pointer (122142719) doesn't
match the backup GPT header's current LBA pointer (0).
The 'e' option on the experts' menu may fix this problem.

Problem: main GPT header's last usable LBA pointer (122142686) doesn't
match the backup GPT header's last usable LBA pointer (0)
The 'e' option on the experts' menu can probably fix this problem.
