Here's a short story: I was burning a OS 9 install disk on my Mac Mini because don't judge me.
When it was done, the disk seemed fine, but it said the drive was "disconnected" after it finished burning.
I looked at the disk (mounted on the desktop, even though I told it to eject) and it seemed fine.
Just to be sure, I burned it again to another CD-R, same error, disk not mounted, drive not ejected.
The drive was in a hub, so I put it into one of the main 4 ports to see if it would mount. Nope.
There isn't a optical drive in Disk Utility or a
/dev, like previously.
