A high-density (1.4 MB) disk you use with your PowerBook computer is not recognized by another Macintosh.

mSome disk drives cannot recognize high-density disks. Try inserting an 800K or 400K disk in the disk drive of the other Macintosh. If that works, copy your files to an 800K disk or a 400K disk. If you regularly plan to use floppy disk drives of different types, use the lower-capacity disks in all drives.

You can’t eject a disk from a floppy disk drive.

mThere may be a temporary mechanical problem with the disk drive. Restart the computer and hold down one of the trackball buttons while the computer starts up. If that doesn’t work, carefully insert the end of a straightened paper clip into the small hole near the disk drive’s opening and push gently until the disk is ejected.

A message says that a disk is not initialized—but you know that it is.

mThe disk may not be seated properly in the disk drive. Eject it and try inserting it again.

mThe 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. If the second disk is also not recognized, call Apple (see the service and support information for the phone number), or take the disk drive to an Apple-authorized service provider.

You can’t delete a file.

mThe floppy disk may be locked. Unlock it by sliding the tab so that it covers the hole at the corner of the disk.

mThe 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.

mAn application program may be using the file. Quit the program.

You can’t save or copy files onto a floppy disk.

mThe disk may be locked. Unlock it by sliding the tab so that it covers the hole at the corner of the disk.

mThe disk may be full. Delete files you no longer need or use a different disk.
