596 GB is the normal usable capacity on a 640 GB drive. Nothing is wrong.

596 x 1024 x 1024 = 624,951,296 bytes. I suspect you may have the balance tied up in System Reserved. Open the Disk Manager and it should show the other 15,048,704 bytes or ~14.35GB as system reserved. Disk drive "market" specs differ from Windows' displays but you're usually getting the full capacity.

That looks fine.

The usable space is only about 93% of the advertised space.

.93 x 640 is 595.2.

You show 596.07 on C, which is close to 595.

The loss is about 7%.

Ops. Yeah, memory fault. The missing space is disk reserved. The 100MB is Windows System Reserved. Sorry.

Alright thanks for your help guys

To put things another way, computers think in powers of 2 (1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, and so on), while people think in terms of powers of 10 (1, 10, 100, 1000 and so on.) To a manufacturer, 1000 megabytes = 1 gigabyte. But a computer says, no ... that's just not right. 1024 megabytes = 1 gigabyte.

Your 640 gigabyte drive = 640,000,000,000 bytes according to the manufacturer. But if you keep dividing 640,000,000,000 by 1024 you'll eventually see it's really 596.046 gigabytes according to the computer. If you were a manufacturer who is selling a hard drive that has 640,000,000,000 bytes, would you rather call it a 640 gigabyte drive or a 596 gigabyte drive?

I have 128GB SSD, a 500GB and 750GB HDD and this is what mine shows.

596 x 1024 x 1024 = 624,951,296 bytes.

Sorry, just wanted to point out a mistake here - carwiz missed one step while going from GB to bytes:

[FONT=Courier New]                     596 GB
x 1024 =         610,304 MB
x 1024 =     624,951,296 KB
x 1024 = 639,950,127,104 bytes[/FONT]

In "marketing speak" that's about 640GB. The 10GB difference is easily explained by partitioning and filesystem usage overhead plus restore points.

I think manufacturers know the real truth,
but their marketing department earn their keep by putting a spin on the truth to make the product look better :shock:

The sequence is
Lies, Damned Lies, Statistics, Marketing

Correction accepted and noted. I was having memory parity errors all weekend. Too much holiday "cheer" I suppose.
