I have wd2500jb.  When I go to format it it says there are only 38 gigs.  How do I get it back to factory showing 250 gig because I want to put XP on it again.  When I have gone to run XP on it it doesn’t give it any more partitions then th eone.  Can someone help me pleae?  I am a newbie at this.

Thanks in advance.
