What does the Message "Input/Output" error mean on Installing Disk 4 Scenery on Mac?

Question

I am receiving an "Input/Output" error message for Disk 4.

I only check the region of USA to keep it simple.

I did confirm Disk 4 has the files- but unable to access it.

Thanks for your help

try putting the disk back in. That’s what I did and it worked.
