Help! My DVD drive is missing!
I was using a laptop given by a friend, and everything was ok until recently. The DVD drive went missing.
Initially, the laptop shows symptom of breaking down. It was not able to write to a DVD or CD, and occasionally it was not able to read. Then one day, it decided not to appear at all in my windows explorer. For a while I thought may be it was over heated, and it should come back after turning off the laptop and let it rest for a while. However, that doesn't work. So thought I could be driver problem. So I went to have a look at the device manager. And true enough, there was a yellow exclamation mark for the DVD/CD drive, indicating that somehow there is an error with the driver.
Further investigation reveals that there are some problem in the registry. So I thought may be I will remove the driver, and re-install again should solve the problem. But it was not as easy as I thought. Trying to update the driver also doesn't help. Finally, after trying all that I could, I decided to google for a solution.
I found one suggested solution is to do something to the registry. Well that might do the job since the error indicated that there is problem in the registry. So I followed carefully the following steps :
1. Click Start, then Run, type REGEDT and click OK.
2. Locate and then remove the following registry values:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClassLowerFilters
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClassUpperFilters
3. Close Registry Editor.
4. Reboot the system for the changes to take effect.
After rebooting, I started the windows explorer, and what do you know?!! I got my DVD drive back. Praise the Lord!
I inserted a CD and it is reading well. I guess I have resolved my missing DVD mystery.
This is recorded for my future reference and also for anyone who faced the same problem I have.
