I would suggest not using any software that came with an external drive. If you understand the basics of copying files back/forth there really isn't a need to use that software. If you are using the drive as a backup drive you might want to try using something like, http://www.crashplan.com/
which will let you backup to a usb drive for free, or a lan drive for free.
I haven't really ever used software that shipped with an external drive so maybe i'm missing the point here. If there is some other function of the software you use please mention it and myself or other likely can suggest another program or method of doing what you need to.
