TOPIC

    My Macintosh DOS Compatible computer ejects Macintosh formatted disks when I am in the MS-DOS environment. This is inconvenient because I am attempting to reformat these disks as PC disks in the MS-DOS environment. Why is this happening? How can I reformat the disks?

DISCUSSION

    Using PC Exchange, the Macintosh environment is able to read and format MS-DOS disks. However, the MS-DOS environment does not have software enabling it to read Macintosh formatted disks. So, in order to prevent accidental erasure of the data on a Macintosh formatted disk, the disk is automatically ejected on the DOS side.*

    To use Macintosh formatted disks on the DOS side, you must first reformat them in the Macintosh environment using PC Exchange. To do this:
      1. Switch to the Macintosh environment using the Command-Return shortcut.
      2. Insert the unlocked Macintosh disk.
      3. Highlight the disk icon.
      4. Select Erase Disk from the Special menu.
      5. Change the format to DOS 1.4 MB (high-density disks) or DOS 720k (low density disks).
      6. Click Erase.
    *Note: The Power Macintosh DOS Compatibility Read Me file incorrectly states that both PC and Macintosh floppy disks are automatically mounted when inserted into the floppy drive in either operating environment.
