I have a HP dv9626us Pavillion laptop, it will not reconize the cd/dvd rom drive, I took a working drive from my wifes laptop and it is not reconized either and the one from my laptop works in her's. Figuring it was a driver problem I reloaded to factory deafults with the recovery CD's. Drive still will not work. also I recently updated bios so I returned the laptop to the previos bios. Still will not work. What should I check next??  Drive has poer and will open and spin up with a disc when installed in my system but is not reconized by my PC. VIST 32bit home permium is the installed OS the the laptop shipped with.

Is the drive seen in the Device Manager?  Try uninstalling and then re-installing it through Device Manager.

Right Click on "My Computer" and go to MANAGE-->On the left hand pane click on DEVICE MANAGER.  This will populate the Right side with all available devices.

Search for the DVD/CD Rom drives and click on the plus sign on it to expand the device.  Right click on the device and select UNINSTALL.  Once it uninstalls RIGHT CLICK at the TOP of the tree and select SCAN FOR HARDWARE CHANGES, this should automatically re-install the device.

Another thing to try is to put in a generic CD (nothing that was burned from another computer)  I've seen burned CD that require proprietary software to read what was burned.  Try using a music CD or something of that nature just to rule that possibility out.

Well I made a knoppix CD and set CD ROM at top of boot order, spins up but will not boot from CD ROM.... so either I have a serious bios issue or the controller is fried on the MB. I really wish HP PC's showed more information in the bios setup screen :((
