You can try to check another DVD opening mode, sometimes it helps: viewtopic.php?f=7&t=28541

I think, external drives do need 12 Volts, and power banks usually only give 5 Volts.

Or is it a slim drive only having USB? does it have two USB cables you would both need to use?

I've had BluRays in the past, where the Bonus Content was on a separate DVD. maybe it's your case as well? If you see a DVD logo on the disc itself, then it most certainly is a DVD.

If you make a backup of a DVD, you can extract the ISO file as the CSS has been removed during backup.

Is that drive connected internally or in an external enclosure?

If internally, can you try to use a different SATA cable? Or at least check, if the cables are connected correctly?

If external, what kind of enclosure is it?

Try using a different DVD opening mode

maybe take out the CD-ROM which seem to be in the drive and keep the drive empty while looking up the info on MakeMKV
