Where have my gigabytes gone?

I'm used to hard drives not actually being as big as they are advertised.

I can't quite recall why it is that, for example, you only get approx 75gb space out of an 80gb hard drive - but thats the case.

But I've just bought a 500gb drive, but only 465gb is available to make a partition out of. Losing 35gb into some black hole seems a bit much to me.

Manufacturers use 1000mb as 1gb windows uses the correct information of 1024mb as 1gb.

  Bailey08787 10:22 05 Mar 2007

using that calculation I should still get somewhere between 488-489gb

465 is about right, my 300gb is seen as 279.47gb by xp.

Can't help. I do agree with you it does seem to be a bit high. You should be getting about 488 gig.
Perhaps someone else can explain where the other 23 gig has gone.
The only thing I did think of was if it was an external drive, some come with software which is preloaded and might take up some space.

I've just read your post, and I seem to have lost 2Gb on my 80Gb hd.
This is good to know though, because I posted the other day about increasing my hd size with Xp, and to whether I would get any problems with Xp recognising the larger size, but if I may loose a few Gb I'll have to allow for it, as I have alot of photos, and a few copies of my dvds on it.

To find out "where your gigabytes have gone" open Computer Management (RIGHT click My Computer) and click on Disk Management. RIGHT click on the drive you are interested in and click Properties. You will then see the drive capacity in Bytes and GB.

Example, I have a drive here of 81,948,430,336Bytes which is also listed as 76.3GB. It is a nominal 80GB drive.

The confusion comes in because the HDD manufactures tend to use the decimal definitions
Kb 10^3, Mb 10^6 and Gb 10^9, whereas computer memory has traditionally been measured in binary so Kb 2^10, Mb 2^20 and Gb 2^30.
So the Gb's aren't lost just hiding.

so its 1073mb per 1gb? and not 1024mb as earlier stated?

Totally-braindead - its an internal 500gb, with nada installed on it.
