Apple Duo 270C manual If you can’t save files on a floppy disk, Backing up your files

Backing up your files

Making backup copies of important files is good protection against possible damage to the originals.

nYou can back up files stored on your hard disk by copying them onto floppy disks.

nYou can back up an entire floppy disk by copying it to another floppy disk, or to a hard disk.

nYou can use a commercial backup program to copy new and changed files from a hard disk to another hard disk, to a tape drive, or to a series of floppy disks.

nIf your computer is on a network, you can back up files by copying them to a shared disk on the network.

nIf your computer can be used in SCSI disk mode and you have access to a desktop Macintosh, you can connect the two computers and back up files by copying them from one computer to the other. (See the chapter on expanding your computer system for more information.)

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:

nMake sure the tab on the back of the disk is in the unlocked position (the square hole should be closed).

nIf you see a message reporting that the disk is full, erase unneeded files from that disk, or save on another disk.

nIf 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.)

nCheck the disk for obvious damage to the plastic case or the sliding metal shutter.

nInsert 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 Apple-authorized service provider for repair.
