Hard Drive Capacity - missing some

I have a 400GB Seagate SATA hard drive.
The entire C:\ drive is formatted.
Disk Management shows capacity is only 372.60GB's.
That's not a good thing, is it......?

In short, Windows is recognizing the hard drive properly and there's nothing to worry about. The confusion lies in the terminology when measuring the volume of a hard drive...see gigabyte (GB) vs gibibyte (GiB).

Hope this helps,

The HDD makers measure capacity on a base 10 scale... So, 1000K = 1MB, 1000MB = 1GB, etc. Your computer measures things on a base 2 scale, so it works out as 1024K = 1MB, 1024MB = 1GB, etc. The rest can be accounted for by filesystem overhead.

Basically, you fell for a marketing gimmick used by HDD makers. But don't feel bad, they bury that way down in the fine print somewhere, and not many people are fluent in binary (base 2) math.
