Every couple years I get a new computer with a new hard drive and then just connect the original hard drive as the second one so I have access to all of my data in case I forgot to back something up.
This worked well with XP but with Vista, I recall this didn't work, there was some kind of security error when I tried to access the data on the drive from a fresh system.
So now I've got a computer with Vista running on a 250GB hard drive.
I regularly back up my most important data, but how can I be sure that if my computer suddenly crashes (currently having problems with my CPU/heatsink/fan), that I have access the data that is on the drive. Is there something I can do, e.g. create some backdoor password, so that I can access the data on this drive by plugging it into another computer as a slave drive?
