Hello. I recently bought a 250 GB Western digital hard drive. I installed it fine since i can use it, but when i installed it i used the software and it said I cannot use all of the 250 GB because of something and it limited me to 137 or so GB. Then i read the package it came in and it said "For harddrives greater then 137 GB, I may need a Ultra ATA controller card. I am quite confused, is there a way to get around being limited to 137 GB, or do i have to buy something on the side? If so, where can i get it... Or can someone show me a site that shows a picture of it or something. Or is it just a download. Thanks.
