320GB hard drive only has 294GB memory what's up with that?

I just bought a brand new x-box 360s with the 320GB hard drive but it only shows that it has 294 total memory and 293 useable memory does anyone else have this problem?

I contacted x-box support and they told me the missing space is the os but WOW that is one huge os I don't see how the x-box has a larger os than my computer

The Xbox 360 OS isn't 26GB, heck Windows 7 is only 6GB.  The 360's Operating system is actually about 120MB.

The reason why you don't get the full 320GB is down to way the formatting of the drive from Bytes to Megabytes is kind of lost in translation.  Let me explain:

Determining drive capacity can be confusing at times because of the different measurement standards that are often used. When dealing with Windows and Mac based systems, you will commonly see both decimal measurements and binary measurements of a drive's capacity. In either case, a drive's capacity is measured by using the total number of bytes available on the drive. As long as the drive displays the correct number of bytes (approximate), you are getting the drive's full capacity.

Decimal vs. Binary:
For simplicity and consistency, hard drive manufacturers define a megabyte as 1,000,000 bytes and a gigabyte as 1,000,000,000 bytes. This is a decimal (base 10) measurement and is the industry standard. However, certain system BIOSs, FDISK and Windows define a megabyte as 1,048,576 bytes and a gigabyte as 1,073,741,824 bytes.

To Determine Decimal Capacity:
A decimal capacity is determined by dividing the total number of bytes, by the number of bytes per gigabyte (1,000,000,000 using base 10).

To Determine Binary Capacity:
A binary capacity is determined by dividing the total number of bytes, by the number of bytes per gigabyte (1,073,741,824 using base 2).

This is why different utilities will report different capacities for the same drive. The number of bytes is the same, but a different number of bytes is used to make a megabyte and a gigabyte. This is similar to the difference between 0 degrees Celsius and 32 degrees Fahrenheit. It is the same temperature, but will be reported differently depending on the scale you are using.

the operating sytem  must takes up 26 gb.if you buy a new pc with a ..say 320gb you never get 320gb because of widows os

Yes we just put ours in WTH?

I would make sense to the end user, but this thing has been going on for years, even Apple uses the same system.  When I bought my '32GB' iPod Touch, I actually got 29.01 of real space.  When I buy my 4.7GB DVD discs and insert them into my PC, I actually get 4.38GB of usable space.

The PS3 uses the same formatting.  Their 320GB console has about 298GB of usable space.

With computer storage it isn't 1000 MB = to 1GB, it's more like 932MB = to 1GB.  You can use that rough guide to figure out the real size what ever storage device you buy. So a 500GB hard drive will actualy be about 466GB.

wow ! you know your zero's and one's obsessive power

I should use a different site this is my daughters but I need some quick information.

I bought my daughter a 320 G HDD  for 45.00 online, we put it in x box and it shows 293 memory

Kinda feel cheated but I told her she still got a good deal and has more memory

Will 27g make that much of a difference? #2 Question will this help with her xbox getting hot?

I'm not talking about downloading the whole game but the software to play them that only takes a few MB

this is exactly what they're telling me now does this sound right to any of you?  every time I download info to play one of the old x-box games it only takes a few MB all the old x-box games combined can't take up 28 GB can it? there are no demos on my hard drive I erased them and still only 294GB

As I understand, you are not getting the full storage size of the 320 GB s hard drive

The available memory space for the 320 GB hard drive is 291 GB. This is less than the total capacity of the hard drive. Some space is used for system information, software that allows you to play some original Xbox games, and game demos.

well they shouldn't call it a 320GB hard drive if it only has 293 they should make it larger to accommodate the used space or market it as a 290GB hard drive
