I have a two disk RAID0 software raid (not hardware raid) that is reported to have failed during boot and my OS won't start.

Using a Live CD, I get the following output :

GParted lists both disks, detects the flags as 'Raid' and lists the data usage.

Can anyone please help me re-assemble just so that I can copy some of the data off that I have not backed up recently?

Thanks
