Re: 48-Bit LBA Support for ATAPI Disk Drives in Windows 2000

FWIW, I think you'll find that the space taken up by the Master Boot Record is
minimal.

I also think you'll find no dishonesty involved in WD statements about drive
capacity and you'll be happy to know that Windows uses the binary system for
abbreviated measurement of files and drive capacity.

BTW, it's now 45 degrees outside where I live. That's an honest statement.
Question: Is it cold or hot outside? You don't know for sure unless you know
whether I'm referring to the Centigrade or Fahrenheit scale.
