  1. My CD player was not being recognized by my computer. My computer went out of a one year warranty on August 14, 2014. HP transferred me to some company in Canada; for out of warranty service. They estimated about $99 bucks to fix the problem and I could sign up for continued help for about $15 bucks a month. I followed these instructions; found and deleted a lower filter (no upper filter was in my system registry) ~rebooted and presto ~ my computer was picking up my CD. Thank you guys so very much. Best wishes.

  2. Hi, I had the same problem. I have Samsung Notebook NP350E5C-SO1IN which is a year old. My DVD drive did not show up on my computer. As I searched for a solution on the internet, I came to know that the problem must be due to Windows 8.1. I tried all the fixes suggested by Microsoft including changes in the registry, checking disk manager (Under DVD icon TSSTcorp CDDVDW SN-208BB which was greyed out, properties showed error 45) for three days but to no avail. That was frustrating. Thought for going to the service center and spend some extra bucks for repair. Then today, I used the support center and did a diagnosis. It showed only one problem (error: boot speed slow). I clicked on the error to resolve it and it showed (Superfetch auto fixing. Enable superfetch to make boot and application speed faster). I shut down the PC as I had to go out for a few minutes. Later, when I switched it on, after a few minutes a popup showed up at the bottom near the hidden icon (sata unknown disk removed) and heard the similar purr of the DVD drive. I checked out ‘My computer’ and the ‘DVD RW’ icon had showed up. I played a cd and it works fine. Hope it stays that way.
    I would request all IT geeks to explain what had gone wrong with my pc and how the problem was solved.

  3. oh, cd/dvd is no show in dev.mgr. but there is cd rom device icon where my E:drive used to be befor it disappeard, thanks

    • Right click on CDROM in Device manager and the click on uninstall and then reboot your computer once. It will be solved. Please revert back if doesn’t.

      • Onlycd/dvd in DEV MGR. is the virtual from Elab Bytes. Only cd/dvd in Computer w/icon is the virtual one. But, CD/DVD is listed in Boot List. No upper/lower filters in entire key. Power is on to disc player. MS says a recent update was tagged with an optical device bug which I think is what killed my Webcam (maybe cd too?) so I need solutions to both. Bless you all.

  4. No filters listed, which is good I suppose, but since I istll win7 ultim 64, no webcam (shows .unknown device’ with updated driver in dev.mgr.) and no cd/dvd even with no 4D36E filters. both are powered but I got Lightscribe and Virtualclone and nothing works or helps…..dogonnit
