Howdy all. I removed a good working internal optical drive from my 2011 iMac 27". Bought a USB cable for it hoping to use it as an external with my 2014 iMac 27" which of course has no internal optdrive. Not sure this combo will work but would be pleased if it does. I plugged the drive into the 2014 USB. Drive has power and inserting a cd went fine. Sounds from the drive indicated normal activity, but no drive icon appeared on 2014 desktop. Without any further actions from me, got a dialog box saying this disk unreadable on this computer (I tried several store bought disks). The dialog box contained offer to eject which I clicked on and the disk ejected normally. Is there something I can do to get this drive working properly in the 2014 imac? Thanks.
