I own an HP Pavilion 9628nr notebook computer. I recently upgraded to Windows 7 from Windows Vista. I was having this same problem in Vista, but I would like to resolve it. Windows 7 is not recognizing my dvdrw drive. I go into device manager and no cd/dvd-rom drives are listed. Also, it does not appear in My Computer. However, I can open the drive, but it will not read a disc. Any help with this problem would be appreciated. Thanks!!
