A message says that a disk is not initialized—but you
know that it is.
nThe disk may not be seated properly in the disk drive. Eject it
and try inserting it again.
nThe disk may be damaged. If you insert another disk in the
drive and the message does not appear, you can assume that
the original disk needs repair. See Chapter 7 for information
about recovering information from a damaged disk. If the
second disk is also not recognized, take the disk drive to an
Apple-authorized service provider.
You can’t delete a file.
nThe floppy disk may be locked. Unlock it by sliding the tab so
that it covers the hole at the corner of the disk.
nThe file may be locked. You can unlock it in its Info window
(choose Get Info from the File menu). Or you can hold down
the Option key while you choose Empty Trash from the
Special menu.
nAn application program may be using the file. You’ll need to
quit the program.
You can’t save or copy files onto a floppy disk.
nThe disk may be locked. Unlock it by sliding the tab so that it
covers the hole at the corner of the disk.
nThe disk may be full. Delete files you no longer need or use a
different disk.
See Chapter 7 for more information about working with disk
drives and disks.
