I am replacing a hard drive for my Dell Latitude CPi D300XT notebook and am wondering if I need to purchase the HD from Dell. On their website it says "NOTE: The computer is designed to work with Dell-tested hard-disk drives only. Use only hard-disk drives purchased from Dell. Do not use hard-disk drives purchased from vendors other than Dell." I know that Dell doesn't make their own HDs, but that isn't the question. I want to know if I can buy a hard drive from somewhere else besides Dell, or do I need to purchase it from Dell in order for it to work?
