I am installing a dual drive kit into a 2009 Mac mini. When I remove the SuperDrive to put in an HDD, would I be able to take my SuperDrive and re-connect it and use it externally with an adapter like this one: https://amzn.to/2Xr3hO3? Thanks!
Sadly your system only has the older USB2 interfaces which is different to the USB3 version, it will be dog slow! There are a few FireWire optical drives made back then, but finding one now will be difficult. I don’t know of anyone trying with this older model, I think it has a PATA not SATA based optical drive but I could be wrong.
