The drive is most likely a 6 Gb/s drive and your system BUS is slower. See if you can use the jumper pins to slow it down so your machine can recognize it. Give us the make and model of the drive and the last three figures of your serial number and we can get you to the correct settings.

Yes - there's something wrong with the cable, connector or drive. You don't state which drive you have... maybe it's SATA speed is wrong for your machine (also generically described). The more facts you give us... the more helpful we can be.
