Why does my hard drive say it has less space than it does?

[Porkchops007]

I have two hard drives, a 1TB sacara barracuda 7200rpm HDD and a 250GB sacara barracuda 7200rpm HDD. The 1TB HDD says it only has 931GB, which I believe is from the NTFS formatting. The 250GB HDD, however, says it only has 116GB available after I deleted everything in it and used the command prompt to reformat it with NTFS. What could be causing this? Is there really only 116GB available?

Thanks,

Here is the command I used to reformat that:
format D: /fs:ntfs

A 1 TB drive has 931 GBs and a 250 has 232 GBs.

The manufacturers go by 1000 = 1 GB

Windows uses 1024 MB = 1 GB

Totally normal.

Use disk management to look at the drives, post a shot it you want.

There are lot of things has been hidden on the drive and you may not able to see it normally. Consider reading the post here about why HDD does this and why you don't have to worry about this:
