Trying to relive childhood and get an Apple //c back up and running. I have the system successfully bootstrapping from ADTPro, but I think there is an issue with my disk drive.
It makes a loud clicking at start up and will not read and disks. ADTPro typically shows an I/O error. If I manually slide the head towards the front of the drive, it will work it's way backwards and sometimes allow me to format a disk. That disk does not boot the system.
I have been trying to come up with a way to determine if the speed is correct, but without being able to make a Copy II Plus disk, I can't check.
Any thoughts or ideas? See the link below for a YouTube of the disk drive at startup.
