Okay here's the deal... i BOUGHT an internal harddrive thinking it was an external one. I can't return it. I want to try to use it but when I opened my computer (something I am not completely new at but don't know EVERYTHING) to install it I hit a problem. I guess the harddrive is a bit outdated and requires a "40 - pin, 80-conductor IDE interface cable". I know what this is but my computer which is basically brand new (less than a year old) does not use a 40 - pin, 80-conductor IDE interface cable. I want to know if there is some sort of converter or way I can use this harddrive; I don't know what the new IDE connecting cable is called for the new computer so I am not sure what to BUY a converter for. The computer I have is running windows 7 and has a Pentium Dual-core CPU E5300 @ 2.60 GHz 2.60 GHz processor. It is an HP. The model is 'HP Pavilion p6110y Desktop PC - NY429AA'. The harddrive is a Western Digital EIDE Hard Drive. it says WD2500JB WD Caviar HD. You should look for an EIDE to SATA converter. Ebay probably has more than a few on sale. Check with your local electronics/computer store, they might carry them.

Hope that helps.You can buy an enclosure if you want to use that hard drive as an external. They're PRETTY cheap. both of those suggestions seem pretty solid, thank you very much guysyeah, get an external usb2 type enclosure. I would personally go demand that they let you do an exchange for a SATA drive. Get a manager, and be a jerk. Sadly this is the best route
