Apple Macintosh PowerBook 145B - Manual (Page 140)

Restoring your System Folder
If your Macintosh does not start up any more, replacing the
System Folder may solve the problem. If you used PowerBook
145B Backup to make a backup copy of your System Folder, you
can use PowerBook 145B Restore to replace the damaged System
Folder on your hard disk with a fresh copy from your backup
disks.
To restore the System Folder to the hard disk, follow the
instructions in the section “Restoring Information on Your Hard
Disk,” using floppy disks containing a backup copy of your System
Folder.
If you can’t save files on a floppy disk
If you can’t save files on a floppy disk, the disk may be locked, full,
or damaged, or the disk drive may not be working properly. Try
the following:
m Make sure the tab on the back of the disk is in the unlocked
position (the square hole should be closed).
m If you see a message reporting that the disk is full, erase
unneeded files from that disk, or save on another disk.
m If you see a message that the disk is not initialized, and you
know that it has been initialized, eject the disk and carefully
insert it again. If the same message appears, the disk is
probably damaged. You may be able to recover its information
with Disk First Aid or another disk-recovery program. (See the
section on testing and repairing disks in this chapter.)
m Check the disk for obvious damage to the plastic case or the
sliding metal shutter.
m Insert a different disk and try saving again. If you can’t save on
the second disk, the disk drive may be damaged. Take the disk
drive to your authorized Apple service provider for repair.
