I already have an extra 160 Gig Maxtor hard drive installed on my cpu, it's empty right now. Compaq 8000T Pentium IV 3.0 Ghz 1 Gb 3200 Ram XP Pro SP2 160 Gb Western Digital Hard drive as primary 160 Gb Maxtor hard drive as secondary, (hopefully as a back up, clone?) My questions: Can I use Acronis 9.0 to clone my primary hard drive to my secondary hard drive as an entire system back up? Do I have to unplug or uninstall my secondary hard drive after cloning? Why is a built in hard drive not recommended for a back up? Can I create a working clone, as a back up, to a second hard drive of the same size that's already installed on my system? Is it ever neccessary to use a floppy for a recovery using Acronis 9.0? (My floppy drive doesn't work at all). If I can create a clone using a built in hard drive is it possible to do a complete system restore from that hard drive? Can I just switch hard drives, after doing a clone, if my primary hard drive fails? (I'm on my 3rd hard drive in the past 3 months, all under warranty, all hard drive failures. I don't want to have to re-install Windows and all my other programs/info if my new hard drive goes bad like the others have). Is Acronis the right program for me? Any and all suggestions would be greatly appreciated. Thanks in advance!
