Apple IIc won't successfully copy disks

I have been trying to make some copies of my important disks, and I go into the system utilities from the prodos system disk, and it never has any errors copying, but I try to boot the EXTRA copy of ProDos that just finished copying, and the new backup disk won't boot! It just goes to a thing with a * at the prompt and I can't use any commands or anything. And it does that with every bootable disk I have, but the regular copies boot fine! What's going on?

Try this

Reverse which drive you read from and write to. Perhaps your drives are just enough out of spec with each other to keep the internal drive reading what the external drive wrote. When making copies, put the original in the external and copy to the internal.

Time to service the floppy drives

As owners of classic, wonderful, and ancient computers it's important to realize that there is some maintenance required to keep these things running well.

The 5.25" floppy drives have two maintenance requirements, which if performed (about every 3-10 years depending on level of use) will make your experiences with them much more pleasurable and easy going.

1) Clean the magnetic read/write heads. (I've already posted how to do that on this board, so do a search.)

2) Adjust the pot (potentiometer) to calibrate the disk rotation speed. On a //c, under the disk drive, there is a small hole in the housing that allows for the insertion of a very small screwdriver (flat bladed ?). You will need a utility that gives a speed reading on the drive and runs it as you make this adjustment. The Copy II Plus program is just one utility that has a "check disk drive speed" routine, there are others.

Performing these two acts bring most floppy disk drives back into "like new" condition.
