Note
The EJECT function offered by various applications for opening the CD-ROM tray
does not work with this drive.
Once you have closed the tray, the CD is tested and the access LED on the drive
starts to flash:
– If the LED flashes continually, the CD is faulty but can still be read.
– If the LED flashes several times and then remains list, the CD you have
inserted is defective and cannot be read.
– The access light is normally on when reading information from the CD.
