I wish to reformat a WD My Passport external disc to a Mac format. Disc utilities respond with "cannot erase the disc". What do I do now?

Mac mini, macOS 10.15

I will suggest two things to try.

Try reformatting the disk in the Safe Mode.
If the disk is now formatted for a PC it likely has a maintenance utility app on it. Use it to first erase and reformat the disk, Then try it with Disk Utility.

If this doesn't't work you may have a defective disk.
