CD-ROM Drive

(Continued)

A Macintosh LC 580

starts up from a

backup CD-ROM disc,

but won’t eject the

disc and gives a -50

error. Or the

computer starts up

from backup CD-

ROM, but won’t mount

discs after restart.

Early Macintosh LC 580 computers shipped with AppleCD 300i

plus CD-ROM drives. Later LC 580 computers shipped with

AppleCD 600i CD-ROM drives. Using a backup CD-ROM intended

for the AppleCD 300i in an AppleCD 600i (or vice versa) will

cause these symptoms.

• Identify the backup CD-ROM discs by their part numbers.

Backup discs for AppleCD 300i have the part numbers

691-0462-B or 691-3305-A. Backup discs for AppleCD

600i have the part number 691-0793-A.

• Identify the CD-ROM drive installed in the Macintosh LC

580. Remove any CD-ROM disc present in the drive. Open

the PC Exchange control panel and click Options. You will

see the product code CR-8004x if the drive is a 300i or

the code CR-8005x if the drive is a 600i.

• Use only 300i backup CD-ROM discs in 300i drives, and

only 600i backup discs in 600i drives.
