Query: no drivers

i purchased this product and found that there was not an installation disk supplied and the drivers are not available from the manufacturer. i own several hp products and in fact i installed this drive in a hp computer. i have never had this problem with any other hp products i have purchased. the drive is useless without the drivers. even my computer's search feature cannot find them. not very happy about this situation.
