Your precious bytes. 1024 = 1000 ?

I never understood the storage memory difference my system showed until I read this

It appears there is a fundamental difference in the way drive manufacturers rate the storage size vs Operating System does. The system sees 1KB = 1024 bytes, but for the drive manufacturers 1KB=1000 bytes and this explains all the difference.

So, the next time you put in a 100GB drive and notice the system shows you only 97.6GB or so, now you know the difference. Snow Leopard now makes this transparent.
