I have a Compaq Ipaq which in the world of hp is pretty much obsolete. My cd drive went out (it couldn't read the CDs). After looking on yahoo answers for ways to trouble shoot the problem I concluded that a new cd drive was inevitable. Overstock was very professional! I was email tracking updates from FedEx and the product was recieved a day earlier! Since Ipaq is built the was a laptop would be instead of the way a desktop would be (hard drive, RAM, CD-rom drives, etc) I had to find a product that was slim line and would slide in with ease. I looked at the non-working cd drive and looked for drives that was the exact same (no back corner missing etc). Ding Ding Ding Ding! We had a winner!Windows Xp recogonized it right away. I put a cd in the drive just to be sure it worked and sure enough it did! Very nice black Friday deal with free shipping! Nice job guys!
