Drive set to "read-only" by accidental registry change. How do you free up the DVD drive so it will be restored to default read, write and edit status?

I was trying to tweak some settings in the registry for display purposes on my machine and one of my DVD drives became "read-only", type #7, a DVD DRU 540A. How do I change it back to a type that would put it back to original default read, write, and edit status? I saw the drives weird status change under computer management in the administrative tools area. I couldn't believe it.

Try system restore perhaps ?
In computer management under storage, removable storage, libraries, right click on your cd/dvd drive and click properties.
Check the settings under the security tab.

Depending on what you did to the registry, you may have to restart in safe mode, log in as admin, and take ownership of the drive.  IT all depends on what you deleted/messed up in the registry. First thing I would try is what kcarrim said, but just wanted to add that you get some security and permission functionality in safe mode that is unavailable in normal load.
