Make sure the hdd is detected by bios. If not try swapping both data and power cables.

Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.
The specific model of a brand name system is shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

The model is often also displayed on a logo (graphical) screen early in the boot, but it's often not as specific as the specific model number.

For Dell computers, they have a Service Tag number - the specific model can be determined by using that on their site, or can often be determined there automatically by you downloading some software. The Service Tag number should be on a label on the outside of the case, probably on the bottom on a laptop, on the back on a desktop, and is often also shown in the bios Setup.

The hard drive must show up as being detected in the mboard's bios Setup.

The drive detection settings in the bios Setup must be set so the hard drive can be detected properly - those are correct by default, but may have been changed - they should be set to Auto detect by the method Auto or LBA, or similar.

If you have an older mboard that supports detecting SATA (a.k.a. SATA I; SATA-150) hard drives but not SATA II (a.k.a. SATA-300) hard drives, some older main chipsets will detect a SATA-II drive anyway but will run it at max SATA specs (up to 150mb / sec burst speed ) , but for other older main chipsets, the mboard will not detect a SATA-II drive at all unless you install a jumper on two pins on the drive that force the bios to see the SATA II drive as a SATA drive.

If this is a new drive, or a drive that has had the data deleted from it, and you already have another hard drive on this computer that has Windows installed on it, the 500gb drive has no data and it will not show up in My Computer or Windows Explorer until it has been software partitioned (using FAT32 or NTFS) and formated.

If you are trying to install Windows on this drive by booting from the Windows XP CD, that's another matter.
- the XP CD must have SP1 or later updates included on it in order for Setup to be able to detect the full size of a hard drive larger than 137gb manufacturer's size

- XP's Setup will detect that the drive has no data on it, if that applies, and software partition and format it before it installs Windows, however...

- XP's Setup will not detect SATA drives after the initial files have been loaded from the CD, unless..

- you have the SATA controller mode in the bios Setup set to IDE compatible mode or similar (e.g. ATA, PATA, compatibilty, etc.) rather than SATA (a.k.a AHCI ) mode.

- or - if you have a legacy floppy drive connected, you press F6 near the beginning of loading files from the Windows CD when you see the line for that, then provide a floppy that has the drivers for the mboard's SATA controller(s) on it, a little later while loading the initial files from the CD.

- or - you make yourself a "slipstreamed" CD-R that has the contents of your CD with the SATA controller drivers for your mboard integrated into it, and use that CD-R to install Windows with. If your CD does not have SP3 updates included, you might as well integrate the SP3 updates into the CD contents while you're at it.
