HD not showing the full capacity

[Bruce Leavitt]

hi

I was noticing the last few times I defragged that my HD didn't show all its
capacity
It is set up

C & D

C: has a a capacity of about 394 but shows 367 available NTFS
D: has about 5g available, and useable about 3.97 FAT (recovery Files)

Seems on C; their is about 24 gigs missing?

Would their be some bad sectors? Is their a way to find it.
I seem to recall when I added c & d up, it was approx 400 gigs., which is
the size of the HD?

Thanks Bruce

It depends on how you measure things. Use your calculator to do this:

367 * 1.024 * 1.024 * 1.024

In other words, nothing is missing and you can stop worrying.

After all these years - this is still not known? ;-)

Details:

Two different mathematical systems are used to define how much information
can be stored on the hard disk drive of your computer: binary or base-2
mathematics and base-10 mathematics.

- In the binary or base-2 system used by the operating system, 1 gigabyte
(GB) is equal to 1,073,741,824 bytes.
- In the base-10 system used by hard disk drive manufacturers, 1 gigabyte
(GB) is equal to 1,000,000,000 bytes (rather than the 1,073,741,824 bytes,
as listed above).

This discrepancy in reporting drive sizes (base-2 vs. base-10) may lead you
to believe that you have a hard disk drive of less than expected capacity if
you compare the figure reported by the operating system with the figure
reported by your documentation, although the actual hard drive size is
identical.
