Hi, I have Nero 7 Ultra, and want to know how good the included Nero ImageDrive program is and what you can and cannot do with it. It says very little about it in the included Nero 7 manual. It says: Nero ImageDrive sets up a virtual drive, which looks like a real drive and behaves in the same way. Says it supports up to two image drives. Is this anything like FirstDefense ISR? Can I run these virtual drives with different sets of software on them and use them for testing different programs safely like FirstDefense? And then just erase them if I want to later? Can I run Nero Image Drive along with other programs like Norton GoBack or DeepFreeze? Thanks very much for any help with this.
