okay, this might be not appropriate since it links to other forums, but I really curious about it source: Need fimware...Anyone have it? Is this really works like that
Yes, it does work like that. There are some reserve sectors and hidden sectors, repair sectors. However, it is not wise to open up those capacity. Drive has gone through intensive test in the factory to make sure the only the best capacity is available for user. Let say u openup an unstable sectors and your OS happen to be install partly there.... you can say bubai after sometime..
Yup, no suprise since some drives share the same platter. Not all drives use the same platters even if it's in the same family.
