It should be a simple problem to fix. I was trying to download a portable program to an external drive (Seagate Free Agent). I tried to make a new folder on the fly and XP wouldn't allow it. I got stuck in some kind of loop trying unsuccessfully to name the folder and then cancel took me back to rename again. Finally I cancelled the download, but folders on the external harddrive were gone. The disk still shows 100+ GB used out of 250GB total. I see recommendations for Recuva and Testdisk as good for file recovery. But I didn't delete any files and nothing has been written to the disk yet. Are either of these programs best to restore the folder and file directories? Or maybe some other fix.
