Linux and My Apple SuperDrive

I have an Apple SuperDrive 2 that would not work on Linux Mint 19. The drive was visible when it plugged it, but would not accept disks. Fortunately I found this article with instruction on how to wake up Apple’s drive and start working.

Here’s the basics:

  1. Install sg3-utils:

    ... sudo apt-get install sg3-utils

  2. Find the device id (likely sr0 or sr1). Mine was sr0:

    ... ls -al /dev | grep sr
lrwxrwxrwx   1 root root           3 Nov 10 11:46 cdrom -> sr0
lrwxrwxrwx   1 root root           3 Nov 10 11:46 cdrw -> sr0
lrwxrwxrwx   1 root root           3 Nov 10 11:46 dvd -> sr0
lrwxrwxrwx   1 root root           3 Nov 10 11:46 dvdrw -> sr0
brw-rw----+  1 root cdrom    11,   0 Nov 10 11:46 sr0

  3. Wake the drive up:
