   Hi   
   Have Powerbook 180, Powerbook G3 and Apple //e with external 3.5 hard drive.    
   I can format a 3.5 disk ProDOS on all 3 machines.  But...   
      
   The disks are not interchangeable.  That is, for example, the disk formatted   
   on the G3 cannot be read by the Apple //e.  Etc.   
      
   Why is this?  I did something wrong?  I am missing something?   
      
   Thanks
