I've been using FD-ISR for a few weeks and I can see great advantages in using it. However, I am concerned after having read on this forum of the experiences of some who have had archives go bad. I am relying on archives on a separate partition as the mainstay of my system restore approach. I have a couple of questions that I hope someone might answer. Firstly, any suggestions as to why they might become corrupted and what one should do to preserve their integrity? Secondly, what advantages, if any, are there to having an external hard drive over an additional internal one in this matter? Last, I'm going to extend my system partition using diskpart.exe so that I can make space to put XP on an empty snapshot. Any ideas as to whether doing this - extending the system partition with diskpart.exe - might adversely affect my use of FD-ISR or back-up software? Thanks for your help.
