I was wondering if it could back up multiple hard disk?
I’m not sure what software you are using. If you are using SmartWare on Windows then you should be able to backup multiple internal hard drives. When you are on the “Home” tab of the software, you can click on the dropdown box and choose the drive that you want to backup. SmartWare will always choose a SmartWare drive as the destination and that cannot be changed.
If you are using a Mac, it currently doesn’t support backing up multiple drives. You can only backup the main Internal hard drive to a SmartWare drive.
