i have a 400gig external usb drive its 3 weeks old and has worked perfectly until now i just moved a folder onto the drive and now it is showing that there are no folders on the drive , i can access the drive as normal but there is no files there, it shows that ive used 165gig of the 400gig when i click on properties . Ive run a disk recovery program which shows all my missing files but i have a laptop with only a 80gig harddrive so the program cant back up the files to my to laptop. Is there any way of recovering my files without using another drive
