Reusing an Apple superdrive with your PureOS Librem

I have an old Apple USB DVD/CD external SuperDrive and wanted to listen to somes CDs while working on my Librem, and although the laptop would detect a usb device being plugged in (/dev/dvd and /dev/dvdrw were created) the drive itself wasn’t being activated. Googling for help I found this little article to unlock the drive.

The solution involves sending a series of byte to the drive to unlock it, and to do this you need to install the util package,

sudo apt-get install sg3-utils

you can then use the sg_raw command to send the magic byte sequence,

sg_raw /dev/dvd EA 00 00 00 00 00 01

(note, the drive was setup as /dev/dvd when plugged in my laptop, ls /dev to check this is the true for you too).

You can setup this as deamon rule, so that the magic happens each time you plug the drive,

sudo nano /etc/udev/rules.d/apple-superdrive.rules

and paste in the following,

# Initialise Apple SuperDrive ACTION=="add", ATTRS{idProduct}=="1500", ATTRS{idVendor}=="05ac", DRIVERS=="usb", RUN+="/usr/bin/sg_raw /dev/$kernel EA 00 00 00 00 00 01"

save it and you’re good to go.

Why waste a good hardware!


Good work.

Many people prefer to convert their CDs to files e.g. FLAC or MP3 and then the files can be accessible from anywhere, on any device, any time - without an ongoing need for a working optical media drive. I use abcde for this purpose.

but that DOES require one to have an optical unit installed and ready …


… as a one-off at some time in the past.

Indeed, and that’s why I need the CD drive :slight_smile:

I rarely use it as most of my favourite music is in mp3 or streaming … but once in a while it still comes in handy.

for those that don’t know yet … mp3 is free right now but i don’t use it because it brings back too many unhappy memories … flac for audio (lossless but can be compressed or left uncompressed) no point in using mp3 unless you’d rather remember the “golden-days” when space USED to BE a problem …

agreed, and I usually prefer ogg for most of my music as the compression for comparable quality with smaller file sizes.

… or you have devices that support MP3 but not FLAC. But we digress.
