G4L - ntfs signature missing
 

So I've got two 200GB Vertex 2 ssd in RAID0 with two ntfs partitions 70gb for data and 50gb with windows 7 installed. I'm trying to make an image before I update the firmware and install linux. But whenever I try to make an image with G4L I get the error "ntfs signature missing". I suspect this is because I'm using an RAID.
Any thoughts?

Thanks in advance!

You're probably right. You might need to make an image of the filesystem, not the underlying device.

I don't know G4L, but you'd get the same message if you tried to mount your RAID partitions with "mount" instead of using mdadm, then mounting the RAID. So you probably have the wrong target for what you're trying to do. If the program cares about it being ntfs, then it's looking at the filesystem level.

Sorry I can't help you with the details for G4L.
