But the process explained there is more complicated than it need be:
Using a PC you will need to download
and the current A09 firmware from the Pioneer web site (1.40 is the current).
Then you flash the drive with the new firmware. You can also turn on the quiet drive "performace" with the quiet drive utility.
If you use a Mac, you will need to put the drive in a PC and do the above. Or you can use VPC and an external USB case for the drive.
