Either your motherboard doesn't support large hard drives OR you didn't partition & format the drive correctly OR your XP disk doesn't include any service packs.

If I recall correctly it took service pack2 to see more than 128gig.

The mboard's bios must recognize the full size of the 500gb drive (it will probably be recognized as it's binary size, which is a bit smaller). If your computer was made in about 2002 or later, then the bios probably does recognize the full size of the drive.

XP must have SP1 or later updates in order for it to recognize the full size of drives, or existing partitions on drives, larger than 137gb manufacturer's size = 128gb binary size in Windows and in most mboard's bioses.
(124.5 gb ? 128 gb is the "raw" size. Software partitioning the drive partition - using NTFS or FAT32 - and formatting it uses up a small percentage of the drive partition space - that space that was used up can't be used for Windows data or user data.)

You could install SP1 or later updates in an existing installation of XP that has no SP updates at all - XP would then see the full size of the physical drive in Disk Management - however, the size of the partition you made will not change, and you can't change the size of it with what's built into XP itself without deleting the partition you made and losing the data on it.
You can, however, use a third party "partition manipulation" program to add the un-allocated space on the drive to the existing 124.5 gb partition without losing the data on that partition.
E.g. The freeware Easesus Partition Master Home Edition

If the existing XP installation has no SP updates at all, you must install SP1 or SP2 updates before you can install SP3 updates.

You will run into this same problem of drives, or of partitions already on drives, > 128gb binary not being detected as their full size whenever you need to use the XP CD that has no SP updates at all - e.g. when you want to Repair something by using the Recovery Console and running a command, or when you need to run a Repair installation of Windows XP.

In order for XP's CD to recognize the full size of drives > 128gb binary, if the XP CD you used does not have any SP updates integrated into it, then you must make yourself a "slipstreamed" CD that has the contents of your CD that has had SP3 updates integrated into them, then make a CD using a certain procedure in certain burning software that can make a bootable Windows disk. You can use that "slipstreamed" disk, preferably a CD-R, to install Windows with, rather than the original CD, along with your original Product Key. If your mboard has SATA controllers and you are using SATA drives, you might as well integrate the drivers for the SATA controllers on your mboard into the contents while you're doing that.

If the XP CD you have has no SP updates, you can integrate SP3 updates into what will be the "slipstreamed" CD's contents without having to integrate SP1or SP2 updates into the contents first.

There are instructions on the web for how to make a "slipstreamed" XP CD and how to integrate SP3 updates into the contents, by using various burning software programs or burning software program modules. If you use Nero Burning Rom 6.x or 7.x, at least some versions have bugs, and you must re-enable a setting just before you burn the disk, otherwise the resulting CD will not be bootable - I have notes about that.

When you have only one hard drive...

Windows Setup defaults to making only one partition on a hard drive (or, a brand name software installation usually has only one visible - in Windows itself - partition on the single hard drive) .
The problem with that is if you ever need to re-load Windows (or the original brand name software installation) from scratch, you lose everything on the partition Windows was installed on, and when you have only one (visible) partition on the hard drive, that's everything on the drive - unless you copy the data you don't want to lose to elsewhere BEFORE you install Windows from scratch (most people don't bother, and lose all their data) .

If you're installing XP from a regular CD, it's recommended you make at least TWO partitions on the drive.
How to make more than one partition on a hard drive, when you're installing Windows on a blank hard drive, or when you are deleting the existing partition(s) on a hard drive before you run Setup .....

If your XP CD does not have SP3 updates included.....

See Response 6
starting at
"If your XP CD does not have SP3 updates included, the best time to load them is right after you have installed Windows from scratch...."

If the existing XP installation has no SP updates at all, you must install SP1 or SP2 updates before you can install SP3 updates.
