I have an apple iic (5.25") and also and apple iie card in a mac. Every disk I put in the apple iic I now get a clicking sound, and the error: "check drive", I've tried the same disks on the apple iie card and they seem to work. I remember reading something about an apple basic command to reset the drive, but can't find it anymore... can anyone help? I have KQ IV, SQ1&2 by sierra on disk, and they don't seem to work on the iie card, but I sure they worked on the apple iic, I want to know if the disks are dead or not.
A few possibilities come to mind. 1. dirty drive head. 2. drive speed too fast or too slow. 3. drive hardware is bad.I've never had much trouble with any of these and I've owned a //c since 1984. Of course it hasn't been used much lately.
You can try the built in test. IIRC you press these keys together. I don't recall this checking the drive but it will verify the basic hardware.
OPEN APPLE CLOSED APPLE CONTROL RESETYou can test the drive with several programs but this requires a functional drive to boot with. Rather a catch 22 here. I suggest Copy2Plus, a very useful utility.
There may also be problems when writing disks on one system and reading them on another. IIRC, this usually was caused by too much variance between drive speeds.
