Just Got My Macbook Pro with 128GB SSD but only 105GB?

[youyou]

Hi People,
So i just received my BTO 2.8Ghz i7 15" Macbook Pro with the factory 128SSD.
Now i know that the OS and whatnot takes up space but is it normal that it taks up 23GB?
My Macbook Pro showed up with only 105GB.
I was sure i read somewhere over here where it should have came with 121GB and from my past readings as well my understanding is that Snow Leopard takes up much less space then previous OS's.
So 23GB off? What gives?
Any help would be greatly appreciated as we all know that any space on a 128GB drive is important.
Thanks in Advance

the os is probably not reporting in binary. you have to convert it. pain, i know, why cant everyone just use the same standard of reporting?

Take a look at DiskInventory X, OmniDiskSweeper or GrandPerspective to see where your HDD space went to.

Also know, that the full capacity of that SSD might not be 128GB. Take a look at Disk utility or System Profiler > Serial-ATA.

Yep, Mac OS X uses the base 10 to report file and folder and HDD sizes. Thus 128,000,000,000 bytes will be reported as 128GB.
If it would use the base 2, it would be reported as 119GB.

Thanks for the quick reply.
Ok so i have no clue what reporting in binary means or how to even convert it.
Any help would be appreciated.
Thanks again

So i went into Disk Utilities and total capacity says 121.33GB ( 121,332,826,112 Bytes )

So what does that mean and is there anything that can be done to get some space back.
Does that mean that my HD is actually 121Gb and not 128Gb?

No need to do any conversions.

Yes, the SSD is actually 121GB, the rest is needed for protecting data.

Gotcha.
So there's nothing i can do then?
Any language packs or any useless stuff i can remove to gain a few GB's?
Thanks again for your help

binary numbering system is based on 2. decimal is based on 10 as im sure you already know.

ex. decimal GB = 1,000,000,000 bytes.
binary GB = 1,073,741,824 bytes.

use this formula to convert the decimal 128 GB to binary... 128,000,000,000 divided by 1,073,741,824 = 119.209289550 minus whatever you have used.

if you format your drive(no dont do this) it should be that size, however i never really checked myself come to think of it. does a clear blank drive report the correct space? hmmm...they could be cheating us and i wouldnt even know. i want every mb i pay for.

You can use Monolingual to remove unwanted languages and Finder to remove printer drivers you don't want or need, as the printer driver for a new printer will normally be downloaded, if you have an internet connection.
If you don't use iLife, you can also remove that and its supporting files.
