No offense, but.... Bullshit! If a drive/controller is working fine, there should be no reason to reformat as often as 6 months. The "magnetic creep" effect is much slower than that, on the order of years. The same goes for the "drifting head" syndrome. If you find that you have to format often, then you have a bad drive or controller. Formatting a drive only hides the problem. If you can hack the possibility that your drive will suddenly not work sometime in the future, it's a band-aid. Also, PLEASE don't use a low-level format as a diagnostic. It should be used when the hardware is known to be good. You can mask serious problems if you do. It'll bite you someday. I know. I've had to reformat my ST4038 twice in the last 5-7 years. Once when I got it, and again when a controller scribbled all over the drive. Same for my Maxtors.
