Windows recognizes it as 243gig but it is saying its full which makes me wonder whats wrong.

1 kb is actually 1024 bytes, not 1000 bytes 2.4% diff
1 mb is actually 1048576 bytes, not 1000000 bytes 4.9% diff
1 gb is actually 1073741824 bytes, not 1000000000 btyes 7.4% diff
if you right click on the drive from explore and select properties, you will
see two sets of numbers for used space, free space, and capacity. the byte
numbers appear to be larger, but actually represent the same number of bytes
as the gb reference.

I bought a 250gig hard drive and I copied over my music collection and a few other things from my old drive totalling around 127gig. Yet now this drive is saying it only has 111gig of free space left even though it says it is a 250gig drive and windows even recognises it as so.
I guess I'm confused, because from this I understand that you copied 127gb from another drive and now Windows says it only has 111gb left free? Is that correct? Now by my calculations 127 + 111 = 238 now this would be 12mb off of 250. Now in your next post I am understanding that the whole drive is being recognized as full? All 243 gigs, is that correct? If the whole drive is being recognized as full and you only transferred 127 gb from the old drive then there is definitely something wrong.

To fix this, you have 2 options :
1. Is to partition the drive into 2 or more partitions so that no partition is bigger than 137GB.
2. You can make XP support the drive fully but you need to do this:
a. Install service pack 1 or later
b. If you already have SP1, then locate the file called atapi.sys in the system32\drivers folder. (make sure you have the 'view hidden/system files' enabled).
Right click on the file & select properties. The version number of this file should be : 5.1.2600.1135 or later. If not, theres a hotfix you can download for it.
If you still have problems after this, let me know.

So to clarify, the total size is 232 GIG (250,056,704,000 bytes) I copied over 127 GB (137,027,936,256 bytes) and now my free space is 111 MEG (116,465,664 bytes)
The drive is a western digital WDC WD2500JB-19GVA0.
When I highlight everything on the drive and click properties (with hidden and system files showing it says size on disk 127 GB (137,027,936,256 bytes) yet windows says I am using 232 GIG (249,940,238,336 bytes)
Cheers for the help you guys. Hopefully I can resolve this, needed the extra space and can't even use it lol!

Also, what type of hard drive is it? ie standard ATA / sata using native sata on mobo / sata on PCI card / USB?

The motherboard is an abit A8V 3rd eye socket 939. I couldn't get any information as to whether or not it supports 48bit Lba even with the bios update. Main problem is I tried running partition magic 8 on the drive and even it says its full so I cant do anything with it in that like resize it or anything like that.
I've sent an email to abit and also to western digital. The hard drive is a western digital WDC WD2500JB-19GVA0 238 gig 7200rpm

Also, does your bios recognise the full drive size?

Are you saying that your bios doesn't recognise the drives full size?
If so, then partitioning it two won't make the bios recognise the drive correctly. Partitioning can force windows to see all of the drive but only if the bios can as well.
In answer to your question - yes there are limitations in both the bios & OS on the amount of drive space they can recognise. XP can recognise a drive of terrabyte proportions I believe, but only if SP1 or later is installed.
Bios's always have limits on this as well. Often a bios update will increase that limit but it's not guaranteed and in some cases, it cannot be increased beyond a certain amount.
Can you tell me exactly what motheboard you have (ie make & model no.)?
Also, have you checked the jumpers on the rear of the drive? Some drives have whats known as a 'size clip'. If this is enabled, it forces the drive to appear smaller than its full capacity in order to overcome bios limitations such as the ones I've mentioned.
