Recover RAW partition to NTFS

Your problem isn't quite clear.
- Which partition can you see? ("iam am able to view files and evrything ok.")
- Check the flags on the partition, and check if the USB HDD is GPT or MBR.

to be more clear. i was a victim of the forced update from microsoft. it updated my computer even though i had automatic updates turned off. after the update my laptop would get the BSOD upon rebooting. i tried all the restore points with no luck. so i bought an ext usb hd and copied the partition from my laptop to the unallocated space on my ext hd. i used gparted from a rescue cd. i verified i was able to see my files on my ext hd. i then wiped my system clean and re-installed windows. i plugged in my ext usb hd and was able to see the 2 partitions on it, FAT32 and the NTFS partition i copied from my laptop that showed up as RAW. WIN7 wanted to format the partition. i could not figure out how to convert it so i put the rescue cd back in, copied the files from the NTFS partion that windows7 saw as RAW to the FAT32 partion on my ext usb hd and rebooted my laptop. win7 now sees the files. so to sum up my problem win7 does not recognize a NTFS partion coped from one hd to another. it sees it as RAW so how do you convert a RAW partition to NTFS without losong data?

Generally, in your case, format this partition is the only way for you to change the RAW file system into previous NTFS.
But, since you have stored your important data there, you can try a free data recovery freeware to retrieve your data back before the format.
You could read more information about it there:-http://blog4mark.blogspot.com/2012/10/convert-external-...
Note: You should not forget to forma it.
You should keep your important data backed up regularly in the future.
Good luck!

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.
