Make sure the drivers are installed. In device manager if they are not there will be a exclmation point with yellow behind it. The drive must be partitioned and formated as well.
If you open My Computer and you don't see your new drive it has not been partioned. You should be able to partion a drive in Disk Managment, if not you can use your windows restore cd/dvd and reboot you computer and partion the drive and then exit.
It has to be formated as well which can be done in disk managment or with windows cd/dvd.
Make sure jumpers are right, They probably are, the drive probably wouldn't show up if it wasn't
