Superdrive ejecting blank CDs

....Apple Superdrive (older from the original box)....

There are two SuperDrives: the MacBook Air Superdrive (Jan 2008), and the USB SuperDrive (Jun 2012). Apple has no specs sheets showing sysreqs for either that I can find, but the MacTracker database† has this:

• • MacBook Air or Mac mini Server (MacBook Air SuperDrive)
  • Mac models from 2008 and later that don't have a built-in optical drive (USB SuperDrive)

If you have the older one, that could be the problem.

Telling the old from the newer is not easy because the model numbers overlap. The older drive could be either model A1270 or A1379. The newer is also A1379/

As you have the box, the label may show the order numbers which don't overlap:

• • MB397G/A, MC684ZM/A (MacBook Air SuperDrive)
  • MD564LL/A (USB SuperDrive)

The MacTracker database also has an even easier to tell one from the other. The cable on the older one is 250mm ( just under 10 inches) long; the newer one has a cable that is 340mm, or just over 13 inches.

And, apologies in advance, but I have to ask because this was a big enough user issue for Apple that they put it at the top of some external SuperDrive support docs: Is the silver side up?

† — Source material: specifications and history are from the MacTracker database, available in the Mac App Store.

Test a Music CD and/or a Movie DVD in the Superdrive.

If those work,

1) try changing the blank CD Preference to "Ask what to do" and test a blank CD.

2) plus I would also test a different brand of blank CDs at this point.

If that does not work,

1) try the Apple USB-C to USB-A adapter.

2) or the following Philips USB-C to USB-A adapter that I have and use.

The blank CD will not show up in Finder unless you direct the operation in the CD/DVD preference pane for it to do something (i.e. open Finer, or another app). However it should not self eject as you noted. Try what dialabrain has suggested.

Dry clean disc for Superdrive?

That might be prudent for an older SuperDrive.
