320gb hard drive only showing 120gb

[metzy85]

i just ordered a 320 gb hard drive from newegg. its a sata drive. I work on computers for the local ballet company and the computer i am putting this in is a hp pavilion a1540n and for some reason the last guy who worked on the computer pulled the sata 1 connector out so i have the drive plugged in on the sata 2 port and its showing up in the windows install as only 130gb. only and in the hp bios it shows as the correct 320gb. What am i doing all wrong??
