FYI, the 640GB hdd shows as +-500GB because of Windows formatting, 1MB = 1024KB, not 1000KB.
So what the manufacturers sell is 640 gigabytes using the "decimal" giga, not the "binary" giga:
640 x 1000 = 640 000 "megabytes"
640000 x 1000 = 640 000 000 "kilobytes"
640 000 000 x 1000 = 640 000 000 000 "bytes"
BUT the computer reads this number in binary!
So 640 000 000 000 bytes divided by 1024 = 625 000 000 kilobytes, not 640 000 000!
625 000 000 divided by 1024 = 610 351.56 megabytes
610 351.5625 divided by 1024 = 596.04 gigabytes.
But if you're very sure you're not get the 640gb, go make report.

TS stated is 640GB in the serial number, but cover shows 500GB and the capacity read from computer is 499GB..
If a 500GB Hard Disk, it should have
500 000 000 000 / 1024 = 488 281 250 KiloBytes
488 281 250 / 1024 = 476 831.158 MegaBytes
476 831.158 / 1024 = 465.66 GigaBytes
465.66 GB only..
