Hard Drive Capacity After Formatting:
That's normal after completing a format as you will always lose about 7% of space. You don't 'lose' anything per se, it's just that the hard drive manufacturers use the metric definition of gigabyte whereas the operating system uses a binary gigabyte (GiB).

Windows always sees 1GB as 1024MB. Hard drive manufacturers define a GB as 1000MB, a simpler calculation.

So, 750GB divided by 1024MB = 0.7324218MB. Now, 0.0.7324218MB x 1000MB = 732.5MB (rounded).

The math is also dependent upon the application used to read the disk, and each may yield a slightly different number. Bottom line: when you start with a drive that's fresh out of it's wrappings, it should be fairly close to the stated number, but it will always be a bit lower than the manufacturer states. Crappy system but that's how they do it.

Formatted capacity does depend on the operating environment & the disk system - NTFS is much more efficient in the size of its disk clusters & wastes less space, so the theory from the hard drive manufacturer put forth is plausible. However, I think you're getting a mix of good & bad information from the public, from various people with varying levels of understanding. Don't blame the tech, necessarily, blame to idiotic math the manufacturers (conf)use people with.

Yes, you got ripped off, but not the way you thought (take what the manufacturers state with a grain of salt & do more research before buying). Add formatting in, and you've lost just a little more - but perhaps not as much as people is saying is normal.

Hope that helps clear it up a little!

If you ever want to know the size of a hard drive after format:
Take the size and times it by 93%. So: 750MB x .93% = 697.5MB usable space left.
Or, you could do the math: 750MB x (1000^3) / (1024^3)

Seagate, Maxtor, WD, Hitachi, Samsung, etc.: 1GB = 1000000000 bytes.
Operating systems: 1GB = 2^30 = 1024^3 = 1073741824 bytes.

So there is about a 73MB difference between the two definitions used.

.93% will fail as soon as you have 1TB+ drives, when the "Magic Number" will be .9%

And the questions will start pouring in. "How come my 1TB drive is only 910GB, WTF!"

And that's when you have to whip out the (10^12)/(2^40) calculations.
