To begin, if you only COPIED files to that external drive then you still 
have the originals somewhere and therefore there is no need to recover 
anything from the external HDD. Right?

Secondly, how do you know that the HDD is formatted in ntfs file system? 
External drives (or any drive, period) normally don't come formatted in 
ntfs. So who formatted it in ntfs? (And which ntfs - the XP version or 
the newer Windows 7 etc ntfs?)

If you were able to copy files to the external, (a) what did you use to 
copy the files?; (b) what makes you think that this HDD is not mounted 
when you now plug it in in Ubuntu?; and, after you plug it in, what do 
see when you issue the command 'fdisk -l' as root in a terminal?
