Sony dru-820a User Manual

Make sure that you use High Speed discs for which this operation has been 
certified by Sony. For the latest information about these discs, visit the user 
support Web site. When using discs other than those mentioned above, the 
drive may limit writing speed to preserve a good reading quality.

We recommend using the drive with the latest firmware as some problems 
encountered when using the drive can be solved simply by updating the drive 
firmware. Firmware updates are available on the user support Web site.

The firmware is the built-in software that makes the drive work.
For details about the user support web site, see page 34.

The default CD-R and CD-ROM read/write speed of this drive is 40× speed. 
With a single touch, you can activate the Turbo Boost function, to raise the 
read/write speed to 48× speed.

• On rare occasions, some discs may not be able to tolerate 48× speed, causing them to break. 

We recommend that you do not use deeply scratched, brittle, or other discs that may break 
at 48× speed.

• The Turbo Boost function does not guarantee a 48× write speed. Depending on the 

condition of the disc you are using, the speed may be automatically lowered.

• The Turbo Boost function does not increase read/write speed with CD-RW discs.

Insert a disc into the drive.

The read/write speed when you insert a disc is normally 40× speed.

Press and hold the Eject button for five seconds.

The Busy indicator blinks twice and the read/write speed switches to 48× 
speed. (The Turbo Boost function is active.)

When you open the disc tray, the read/write speed reverts to its default of 40× speed.
