used gparted to copy partition from windows7 laptop to usb ext HD as ntfs partition. iam am able to view files and evrything ok. when i reboot into win7 it sees partition as RAW. its says i need to format it.
There isn't a way to change the partition from RAW to NTFS and keep all the data intact.
There is a method that you might be able to use to get to the data mentioned HERE
. It's definitely worth a shot.
