I originally posted these questions at the end of another thread with a totally different title, so I thought I'd start a new thread with a title appropriate for the questions. I have a second internal drive connected so I want to try doing a system drive recovery to the second drive. Could you please answer a few basic questions for me regarding the process so I don't do something stupid along the way? My goal is to try to restore the system onto the second drive after swapping it into the old C drive location and use the Acronis boot disk to do the restore. I think that most closely resembles what I'd have to do in the event of a catastrophic failure (as opposed to making a duplicate copy on the other drive with the current OS intact and then swap the drives after doing the restoration without using the boot disk) My second drive currently has only one partition (G) for the entire drive (200GB). So the first thing I'll have to do is add another partition similar in size to my current C: partition, which is about 34GB, so that shouldn't be any problem. I have Partition Magic to help with that. My first question is this: If I add a new partition (F) *before* the existing G partition, what actually happens to the existing data in the G partition? I think the current G partition starts at the 1st sector on the physical drive. Will the new F partition actually allocate physical sector space after the current G partition, then just logically map it with a new MBR table entry to point to the first sector location? Or will the re-partitioning actually move the existing G data on the drive, and physically place the F partition at the 1st sector? I hope its the latter, because I think when I restore the system image onto that drive it has to reside at the first physical sector because that's where Acronis will place the MBR from my original image, right? And as long as I made the new partition bigger than the original C partition, that space will be available to restore the system image without writing over any of the old G partition data that I don't want to disturb. Next question: Does the drive that contains the OS/system code always have to be hooked up to the first position cable so the boot process can find the MBR? I think it assumes sector 0 on the first disk it finds will have the MBR, but I'm not sure. So I think that means I have to swap the cables on the two drives when I do the boot/restore. Next question: The old MBR that will get restored knew about the F and G partitions when that drive was connected to the other cable, but now that the cables have been swapped between the drives what impact will that have on the MBR data? Will the PC be able to recognize the physical disk and determine that its been swapped, and adjust the MBR info accordingly? Will the old F and G partitions now be called C and D? And what about the partitions on the old C drive, will they now start at E? I assume the PC must be able to figure this out upon boot, otherwise the old MBR would be worthless in the restore process. So given all this uncertainty, I think all I have to do is this: 1) add F partition to 200GB disk 2) swap the disks 3) reboot with the Acronis boot disk 4) follow directions to restore the system image from my old C drive 5) reboot again to see if it worked Given what I've described above regarding my system, will I have to do anything else? thanks in advance!!
