are reported by OS X, up until Snow Leopard, using the 1024 method (Binary).
Apple changed the procedure with the launch of SL and this brought Apple in line with the drive manufacturers and other OS producers.
The Drive makers have been using 1000 (Decimal) as their measure for a considerable number of years, it's not new.
The drives are exactly the same size as they were before, just measure in a different way.

Hello. I work a lot with video, DVD's, etc. This work relies heavily upon the long-time, established standard when it comes to file sizes; that is, that noble of all numbers, 1024.
Sadly, it appears that some computer makers, hard drive manufacturers, and even some ISP's, no longer have respect for the decades-old standard of 1024, upon which the computer industry was built. Thus, to earn a higher profit, and to pretend to offer more than they really are, they have chosen to use 1000, instead of 1024, as their unit of measurement. It makes Internet speeds appear faster than they really are; it makes hard drives seem bigger than they really are; etc. To me, it is plain old greed and deception.
For someone involved with video, where accurate measurements are required, this modern usage of 1000 presents a problem.
Thus, I am looking for a program which will allow me to display REAL file sizes in the Finder -- which relies upon 1024k/Kb, 1024Kb/Mb, 1024Mb/Gb, etc. -- rather than the more modern approach of 1000 units/whatever.
I was hoping that a program like MacPilot, or a similar app, might possess this tweaking feature, but I have been unable to find one to date.
The only thing that I can do for now is to use a program like MediaInfo, which is a halfway point, because I actually want ALL of my files on my hard drives to display the file size based upon 1024, and NOT upon 1000.
Can anyone else?
