Just bought new WD15EURS 1.5TB . In Bios and Win XP SP2 shows only 500gb. Tryed on new PC with Win 7 - same showing 500 GB. Any help here?

What does it tell you your drive is (model number etc.)? Also where did you purchase the drive?
Your question is a FAQ.
If you have a Gigabyte motherboard with an Xpress Recovery BIOS, then see the following thread for an explanation and solution:

Some Asus motherboards appear to be similarly affected:
