Is there a good method to guard against images that may be corrupt, either because of failing hardware or faulty software? In the past I have had files that experienced corruption and I never new it until I tried to access them. Thankfully they weren't anything critical.
I currently have my photographs and videos on a RAID 1 partition in my computer and then also back them up to an online storage service. I am using my motherboards Intel RAID driver though and it seems kind of unstable since I activated it. I am now thinking of buying an external RAID 1 box.
Any thoughts or suggestions?
