Hi there, I recently updated my HP Pavilion DV2810US (or DV2500, same thing) from its original Windows Vista (32 bit) to Windows 7 (64 bit). My problem since I upgraded was that my CD/DVD Optical Drive (which is a LightScribe Super Multi 8X DVDÂ±R/RW with Double Layer Support) doesn’t read my cd/dvds. I don’t know if my optical drive is messed up or some cable is messed up (I had a friend install a new hard drive so the computer was opened). The thing is, when I insert a CD or a DVD, the little light turns on and the cd spins and tries to load but nothing happens. I have read on multiple forums to check “Device Manager” and look for my drive but ITS NOT THERE! Nothing shows up, also Itunes or Lightscribe doesn’t detect an optical drive? What can I do? Can somebody help me please? Could it be that my drive doesn’t support 64 bit windows 7? Any help will be appreciated.
