Is there a command line to check blank DVD (or CD) Media for
imperfections before burning?

Not that I'm aware of. The media is blank. Being a write-once medium,
there's literally nothing on it until you write something to it. There's
nothing to read, and a write test is destructive.

I used k3b to copy DVD. That went well until halfway through the burn I
got message that the media was bad. I then had to start all over and
copy the original again. Thankfully the next blank DVD was good.

That happens. You can reduce the risk of failure, saving yourself time and
aggravation, by purchasing writable media made by name brand outfits (ie
Verbatim, Memorex, etc). The cheap off-brand stuff comes with a greater
risk that the write will fail and you'll get a coaster.

By the way, the same is true of multi-write flash media like SD cards. The
old adage "you get what you pay for" has always held true for me in these
spaces.
