Problems with hardware
Floppy disk drive (either an external drive or built into a dock)
I can’t eject a floppy disk.
mThe disk may be stuck. Restart the computer, holding down the button on your trackpad. If the disk is not ejected, you can eject it manually. Carefully insert the end of a straightened paper clip into the small hole near the disk drive’s opening, and push firmly until the disk is ejected.
I can’t save or copy files onto a floppy disk.
mThe disk may be locked. Unlock it by sliding the tab at the corner of the disk so that it covers the hole.
mThe disk may be full. Throw away items on the disk that you no longer need, or save the files on a different disk.
mThe disk or disk drive may be damaged. Test the disk with Disk First Aid. (You can find Disk First Aid in the Utilities folder on your hard disk, or on the Disk Tools disk that came with your computer.)
Hard disk
The computer won’t start up from the internal hard disk, or the hard disk icon doesn’t appear on the desktop.
mThere may be a temporary software problem. Turn off the computer, wait at least 10 seconds, and then turn it on again.
The hard disk keeps stopping and starting again.
mThe hard disk may be going to sleep to conserve power. Use the PowerBook control panel to change the power conservation settings.
