...First of all it was joke to take it to an mri machine. If you didnt know what an mri machine does, it magnetically (with high powered magnets) can be used to scan parts of the body. If your comp got anywhere near the inside of an mri machine, every component, including ur hd would be wiped. On the other hand I really do format every other week. I like having a clean state. I dont really keep much of anything on my hd... and the things I do are just transfered over. I dont know why you think formatting is some big thing...
