Ah, so you used hard disk manufacturer's "lying" gigabytes... <grin>

A bit is a single one or zero. A byte is eight bits. A kilobyte is 1024 bytes. A megabyte is 1024 kilobytes, and a gigabyte is 1024 megabytes.

So, in that case, 100461300404 bytes/1024 comes out to 98106738.68 kilobyes.

divided again by 1024 to get 95807.36 megabytes...

divided again by 1024 gives us 93.56 gigabytes.

100 gigabytes = 107374182400 bytes.

<grin>
