I would like to run a practice of a system restore to prepare for the event should my main SATA HDD fail. I will restore the backup image of my system partition (C Drive) from an external USB drive to a primary partition on my second hard drive using UBCD4Win. I will use Paragon Backup & Recovery 10 and I'll probably also try Macrium Reflect Free. XP Disk Management does not allow me to make the primary partition on the second hard drive active. Can I make this partition active and leave it that way without causing problems? I can change the BIOS so this drive is not in the boot sequence. Is it better to wait and make it active as part of the restore procedure? Any help would be appreciated.
