2 months ago I backed up all of my images on a disk and can no longer find this disk. I upgraded to vista. I'm pretty sure this is impossible but is there any way to get these images recovered at all?
Try the software from here http://www.easeus.com/download.htm (You can try this for the second. I would suggest using the Trial version to see if you have any files you can recovery. The Trial version does not allow you to save them, but if they are there you can then purchase it (if it is worht it to you)
