So I started to boot my system and it blue screened, accusing mrtrate.sys as the (possible culprit). I really could not find much information about this and I really did not have the time or the patience to research the crash. It was 6 in the morning and I had to go to work. But! TGFB (Thank Goodness for Backups). For the past 4 years or so, I've been using Symantec Ghost (v10 with my XP system and v15 with my Win7 systems). Ghost starts off by creating a full system backup and then differentials after that until the next cycle begins. In my case, I booted from the Ghost CD and performed a full restore from the last full and then the differentials stored on an external USB drive, and 2.5 hours later, my system is back. The bootable CD allowed me, with a Command Line prompt, to copy any files created after my last backup, to a USB drive before the restore. My advise, if you have a backup solution, make sure you can restore from it with as little intervention or pain as possible. I am also a customer of Carbonite just in case my system and backup fail. Any tails of trials and tribualtions pertaining to recovering a failed system.?
