*HELP* - Hard disk - incorrect CAPACITY

I’ve read that before, but notice this screenshot

Notice the CAPACITY and FREE SPACE reported under COMPUTER MANAGEMENT, and the capacity reported by the disk properties is different?

Furthermore:

Command line CLEARY RECOGNIZES that there are 493 GB of FREE SPACE !!!

Does that mean if i copy files using command prompt, i can use up the full capacity?

Here’s the different capacity report

  • Local Disk Properties

    Capacity: 500.11 GB          Free Space:  493.45 GB

  But it is “rounded up” to

    Capacity: 465 GB                Free Space: 459 GB

  • Computer Management

    Capacity 465.76 GB           Free Space: 459.55 GB

  • Western Digital Data Lifeguard Diagnostic

    Capacity: 500.11 GB          Free Space:  493.45 GB

  • Bios info

    Capacity: 500 GB

  • Command Prompt

    Capacity: 500 GB                Free Space: 493 GB

Clearly Windows XP is able to see the correct capacity under command prompt.

But for some reason, it reports the  wrong capacity under windows explorer.

Isn’t this strange?
