Fortunately I had a few K Hypermedia CD-R disks that worked satisfactorily to make the system repair disk.

The M-disc compatibility was the big selling point for me, as I have had DVD-R media go bad, making discs with irreplaceable material unplayable

I purchased this hoping it would be a higher grade disc drive, and it did in fact read a critically important DVD-R that numerous other internal and external drives failed to read.

I didn't bother to install the DVD writer software provided as I have a favorite I always use.
