i bought a external hard drive from dell. installed the software for it and ran the back up for all my files and such. now it doesn't show any of them on it for us to install on the new hard drive we had to install.
Post the model number of the drive; we can try to locate a manual. When you start the software is there a "restore" option - and if so, does it list the files on the external drive?
Also, all OEM's (or at least every one I've seen) provide a utility that allows you copy the content of the old drive to the new one. If you don't have a CD you can download the utilities from the OEM's web site.
