Data Loss

Well i got some movies from my friends laptop which runs Ubuntu in my porteable hdd.
But when i plugged it my windows 7 machine it shows that the disk needs to be formatted.
first i thought it must be different file system so i downloaded a linux file viewer but it still shows the file needs to be formatted.
is there any solution to this problem?
thanks in advance guys
edit: my hdd is compatible with win7

Is your drive formatted as ntfs or ext2 or ext3 file system. If it is formated for linux than try these program for reading files http://www.fs-driver.org/

Answer #4
You could try downloading ubuntu and running it (it has a live CD function) to see if it will open the files first. If it works, try transferring the data from the drive to your windows 7 drive using ubuntu, or any linux distro.
Ubuntu can be found here http://www.ubuntu.com/getubuntu/download
Alternatively use Puppy linux, (A dedicated live CD OS) found here:

His drive is probably corrupted maybe ubuntu cant read files,try to use some data back program if that can help but i think that you will need to reformat drive.
