External DVD recognized as removable disk

[cpliu]

I have this setup (generic internal DVD writer put in a external case
with firwire connection) that worked fine in the past. I took the DVD
out and connected to another PC so I could install a game from the
DVD. I put it back and now my regular PC recognize it as removable
disk instead DVD.

How can I get it to work again?

Thanks,

Fixed. I forgot that I changed it to slave for working on another PC.
Once I changed it back to Master, it's working properly now.
