I performed a full recovery to factory settings on my Windows 7 machine. Before doing this, I performed a backup onto my external 500 GB Seagate drive. After the recovery process, I am now trying to restore my data from the backup on the external drive. However, Windows does not give the external drive in the list of backup devices. If I click on "refresh," it doesn't find it. I do see the drive and its folders in Windows Explorer. Also, if I go to "Set up backup," Windows does list the Seagate drive as an option to use for backup.
