For no apparent reason, my CD/DVD combo drive sometimes disappears after having used it during a windows session, and some other times, it doesn't appear at all after booting up.
What I have checked already:
I read somewhere in the WIndows support forums that it is possible that the drive might not be compatible with Windows' AHCI drivers. Can anyone confirm, please?
The model of my drive is:
Module,Dvd+/-Rw,16X,BARE,Precision Workstation,Toshiba Samsung Storage Technology
Follow below steps to resolve the issue.

If upper filters and lower filters are still missing you can go ahead and run the Microsoft fixit.
I have provided a link to run Microsoft Fixit:
Awaiting your response!
Thanks for your prompt reply. I happened to have a spare SATA cable so I changed it yesterday and I haven't had issues so far. I will try to use your solution if the problem reappears.
I peeked on my computer's registry and I do have the "LowerFilters" entry, but as mentioned above, I am going to wait and see if the cable swap solves the problem.
