New hard drive problems

#1saltal3220Posted 2/17/2013 4:07:42 PM
So I have a 60 gig fat model and I went to best buy to get a new hdd. After installing and formatting a 250gb hdd it only had 205/232 gigs of free space. I know you never get the full amount that it says on the box but where did that other 27 gigs go? It should have said 232/232 as far as I know. Is this normal?

That's normal. That's just reserved space for your PS3.

It's because bytes don't work on a based 10 scale, they work on a base 2 scale.

1 kilobyte = actaully 2 ^ 10 bytes, = 1024 bytes.
1 megabyte = 1024 kilobytes
1 gigabite = 1024 megabyes.

1 Gigabye = 1024 (megbyes) * 1024 (kilobyes) * 1024 (bytes). Therefore a gig is actually 1,073,741,824 byes.

Therefore when something is advertised as 1 gig, is is actually 1,000,000,000 / 1,073,741,824 = 0.931 gigs.

So, in your case your advertisement of 250 gigs is actually (250 * 0.931) = 232 gigs, as you've quoted above.

I know it doesn't make a lot of sense, but that's how it works. When you buy a drive of 'x' gigs, you need to multiply 'x' by 0.931 to get the real, base 10 size.

He means why it only has 205 GB.

Oh, so he does.

Oh well, at least I've explained where the other missing 18 gigs went.
