I'm seeing several slimline optical drives sold by Dell or by other sellers, but didn't see any that were for the T5810.
Questions: 1. What was the part number of the original DVD +/- RW drive that came with the T5810? 2. Can I use a drive that's for a different machine, like for the T7820, for example? 3. Is there anything special about these slimline drives, or the fitment into various models because I see quite a few models. 4. Would any from this page be suitable: https://www.dell.com/en-us/work/shop/cd-dvd-internal/ar/7853
