I think I have seen explanation before, but I don't remember the details.
I bought a 9.1GB drive and according to the specification it's 9.1GB
formatted. But, after I formatted it, it showed up as only around 8.5GB. Do
HD manufacturers use different scale system than most OSs (e.g., divided by
1000 instead of 1024 so their numbers are always bigger than the actual
number shown on our system)? Why do they continue to do that if I rember
the reason correctly? Similar to what they're required to do with Monitors
(i.e., advertise 17 inch monitor, actual viewing size = 15.9 inch). Should
HD manufacuturers be required to use 9.1GB formatted size, actual usable
size = 8.5GB???

Any explanations on this?


Thanks,
