hey, i was wondering if its possible to be running off a hard drive, then switch over to other hard drive? of course information on the different hard drives wouldnt be should, dif registrys, dif programs/files, and i dont think im tlaking about partitions becuase if i am correct u cant add/change files to partitions? and if it is possble just to switch over hard drives at startup (setup in bios) like switch the boot priotitys? that would be just wodnerfull :lol: . and i mean switching over hard drives WITHOUT taking a hard drive out and putting a hard drive in. back to partitions. if it is possble to have 2 different partitions with 2 different operating systems that would be nice, becuase one system i might want my space on. REASON. if one hard drive/system fails the other is perfectly fine (nothing to do with backup).
