Ah, I meant for inspecting the disk to look at it. I was thinking I could use DSKI$/DSKO$ to move the sectors (though I bet ColorZap does that too, if it's like dEd).

COOL!  - I only saw DSKCON being used in a BASIC program recently, when I was going through old disks and found some software by Joel Hegberg. I do not remember ever knowing how to do that.

This would get around I/O ERROR on a CoCo 1/2 (without the ON ERROR command).

How do you detect an error? I assume there's a status byte you can read somewhere?
