Having had two consecutive disk crashes last summer, I decided I had to take steps to protect me from going through the same nightmare again. I started downloading Paragon B&R 10 free, and studied it. Then I did the following: I equipped my computer (running XP Pro) with two identical 500 GB internal drives, identically partitioned with four partitions each: one for the OS, then the installed Programs, then the Data, and finally Downloads (respectively: C,D,E,F; and G,H,I,J for the two disks). I already had one same size USB external disk. My intention was to use my USB disk to make a weekly backup of the first internal disk, and then to do a restore operation to the second internal drive. This way, in case of failure of the first drive I could easily switch to the second, finding practically the same content as in the first, though one week old at most. Being however rather unfamiliar with backup/restore techniques, I feared that the transition from the first to the second drive would not be very quick. I thought in fact that, most probably, for the system to boot properly, I had to rename the G,H,I,J partitions in the second drive as C,D,E,F, like originally in the first drive; and also that I would have to physically connect the second drive as a master disk, like the first disk was before the failure. But here was the surprise. When I started experimenting to test the procedure, I first discovered that my system BIOS allowed me, if properly modified, to choose which disk to boot from. But an even greater surprise was to realize that, by simply changing the BIOS booting instructions, the computer would immediately boot correctly from the second drive, with no need to rename its partitions. This of course made me, at least for a few moments, the happiest person on earth: the procedure suddenly became extremely simple and the recovery practically immediate! On second thought, however, doubts arose in my mind: is this real, or perhaps I am getting hold of the wrong end of the stick? Am I seeing things? Is it possible that the partitions in the second disk get renamed automatically? As much as I experiment, everything appears as I described it. Can anyone in the forum explain how things go really?
