I have a 500 GB HDD in my laptop, but when I add up the partitions, they take up 465GB, and there are no unallocated spaces anywhere. Where did that 35GB go?

This is what my HDD looks like in the Windows partition manager:

enter image description here

As you can see, the space used is 0.6 + 0.3 + 409.19 + 37.25 + 2.79 + 15.53 = 465.66GB. On the left, Windows does indeed report the size of the drive as being 465 GB, but I know for a fact that this is a 500GB HDD, unless Newegg, Ebay and Amazon all made mistakes. Can someone please help me get back the 35GB I'm entitled to?

Note: I do know that the HDD has 7 partitions, even if only 6 are shown. The one that you can't see is Microsoft Reserved, and is very small, so that's not what is missing.

  • Who told you it was 500GB? (Most things get rounded up. a 460GB disk will be sold as 500GB.). 2) Did you correct for GiB vs GB?

  • Newegg lists it as 500GB, as well as Amazon. – superchampionoftheworld Aug 26 '17 at 16:26

    Here's something interesting. 500GB is exactly 465.66GiB. Wow. I probably would have checked for this, if the partition manager said GiB instead of GB. Thanks for the help. – superchampionoftheworld Aug 26 '17 at 16:29

    Windows uses base 10 to report the size of a HDD. Additionally there is overhead for your file system. Additionally HDD manufactures (check the HDD box as proof) advertise GB in a different way then Windows calculates them. In other words 465.64 GB is 100% of your HDD disk space. – Ramhound Aug 26 '17 at 16:30
  • I can't seem to find the duplicate to this question exists. I cannot remember the title of it. – Ramhound Aug 26 '17 at 18:38
