I have a laptop( sony running unbunt 10) with data installed on a raid 1 setup, the lap top has died. I would like to recover the data from the disks. I have been able to plug the disk in to a desktop system using a state hard drive mount adaptor.

Doing an fdisk -l reports the drive, but list it as an unknown partition table[ a dmesg dump is given at the end].

The dive is a Fujitsu as listed by dmesg, so I am assuming from this that the drive is ok and that the data is laid out as a raid file system. I had assumed that use of raid 1 disk would result in the contents off disk 0 being the same as disk 1.
My question is what options should I quote to things like fdisk to be able to tell it do understand the format of the disk.
The laptop is about 3 years and for the cost of getting it repaired, I could have a much faster machine, hence the interest in just getting access to the contents of the disks.

Any suggestion as to what to do next?
