Windows. You can now use your CDR(W) or DVD recorder
for file storage and retrieval as if it were a hard drive
or floppy disk.

Refer to the on-line help for configuration and formatting
DLA may not function properly if Auto Insert Notification
(AutoRun) is disabled. If you encounter difficulties with
DLA, please ensure that the AutoRun feature of your
operating system is enabled."http://dl0.sonicjapan.co.jp/dl/SonyDrive_D.../readme_ENU.txt
If you want to be able to use Windows to write to the cd drive DLA must be enabled and in the startup menu according to this tutorial.
Don't get too overconcerned about necessary programs or processes running (those that enable the way in which you wish to use your computer).
