You sure? Make sure the disc you are using can be read at 48X, so for instance don’t use an audio or CD-RW disc. Data can be read at 48X with SpeedRead. This is how you should enable SpeedRead for your drive manually (just to make sure you did it correctly):
-Open the drive tray and make sure the drive is empty.
-Close the tray again.
-Press and hold the eject button for a few seconds and wait till the LED flashes four or five times, then let go of the eject button.
-The tray opens, insert the disc and close the tray.
-SpeedRead is enabled.
Did you do it this way? Please note that when you open the tray again, SpeedRead will be disabled again. When you cut the drive’s power it will also be disabled again. Does it work?
