Lost data

I bought a passport to back up my gateway hard drive. I had to reinstall windows but when I went to reinstall from my passport backup all my data was erased and replaced with the data from the reinstall. The backup was useless, I guess I have a $90 blue paperweight.

I asssune you used Smartware. Was the drive connected when you reinstalled Windows? Did you check for hidden files? Check this post http://community.wdc.com/t5/My-Book-for-PC/data-restore/m-p/161586/highlight/true#M5703
