You cannot mount the Mac OS–, DOS-, or ProDOS-format partitions of an external SCSI

hard disk or a removable media cartridge as individual volumes on the desktop.

Use Macintosh PC Exchange to mount these partitions as individual volumes
on the desktop. (Macintosh PC Exchange is a control panel that is part of
system software. When used with a DOS-compatibility card and its
accompanying software, Macintosh PC Exchange allows your Macintosh to
communicate with non-Macintosh software and hardware.) If the disk
contains both Mac OS– and DOS-format partitions, Macintosh PC Exchange
will recognize only the Mac OS partition. Also, Macintosh PC Exchange can
only recognize ProDOS-format partitions on SCSI hard disks that are less
than 32 MB.

You cannot resize or reformat the Mac OS–, DOS-, or ProDOS-format partitions of an

external SCSI hard disk or a removable media cartridge.

To resize or reformat multiple Mac OS, DOS, or ProDOS partitions, you need
to use third-party software designed for partitioning hard disks and removable
media cartridges.

You cannot unmount and eject an external removable media device such as a cartridge.

The Eject Disk command is unavailable when you are working with
removable media devices. To unmount and eject a removable media cartridge,
click the device’s icon to select it and choose Put Away from the File menu.
Once the device has spun down and its light goes out, you can manually eject
the cartridge from the drive. To access a removable media cartridge that has
been ejected, simply reinsert the cartridge in the drive.

Your Macintosh can’t read a floppy disk.

If you see a message that a floppy disk is unreadable, try one of the following:

m If the disk has never been used, you may simply need to initialize it. For

instructions, see the “Disks” topic area of Macintosh Guide, available in the
Guide (h) menu.

m The disk may be damaged. See “Testing and Repairing a Damaged Disk”

later in this chapter for information on testing and repairing disks.

m The disk may have been formatted for use on another kind of computer.

You may be able to use a program that lets you work with such disks on
your Macintosh.
