500GB HDD only Formats to 450GB

[David-Baugham]

I have a Western Digital Blue 500GB HDD ( WDC WD5000AAKX-22ERMA0 )
That Only want to format to 450GB. It Previously came froman Acer Desktop that Died, and I wanted to Use It as a Steam Drive. So Is there anyway It can Be reseted Or Formatted to 500GB of space?

Firs, you need to go to the disk manager and see if there is a hidden partition. If it came from an acer, there is a chance they had a hidden partition for restoring from.

Also factor in a HD you don't get proper size. Taken from here http://www.tomshardware.com/forum/286241-32-computing-capacity-format

You loose 7% due to the real definition of a GB, so 500GB*7%=35GB, so even with any hidden or system partitions, max size will be 465GB anyways.

Thanks for your help, I'll bookmark this Thread in the future when I need those 15GB of space.

Yep.
Two reasons:

1) binary vs decimal size difference (the higher the capacity the more obvious the difference)
and
2) Formatting (data used up on the drive to create the file allocation tables etc)

Other:
As said, check Disk management to see if there's "unallocated" data or a small amount of data as a partition. Simply DELETE everything you see so there's a single partition.

*I suggest you run CHECKDISK on the drive. Open command prompt and type:
chkdsk C: /f /r /x

Will take hours. change drive letter as appropriate.
