I am fairly new to using the external hard drive. I recently completed a backup after months on not having backed up. I ran the WD Smartware and backed up all files on both my C and D drives. Mostly music and photos. After completing the backup, I went to verfy that the files were on the drive, but I cannot find them. It only shows the files from my first back up. I cannot find any of the 30 GB worth of files that it supposedly just backed up. Can anyone help?
