Disk drive utilization

[alem20]

I have bought 500GB of hard drive but only 149GB is recognized by my PC. I am using Win xp and Win 7. in both OS the same value is recognized.

Have you tried reformatting the hard drive?

What brand and model number is it?

It may also be helpful if you let us know how you partitioned your drive;

For example, did you partition it using the Windows XP installation disk?

If I recall correctly, 150 GB was somewhere around the max space Windows XP would recognize before SP2 during install.
