Update firmware in my SONY DVD RW DRU-720A

[leoliver]

Hi Everyone,

I decided to update the firmware in my SONY DVD RW DRU-720A external USB
drive . I want to update to JY08 , from JYC4 . The reason for the update is
to the new firmare will enable to write to Sony DW+RW DL disc's.
Sony says I must disable DMA for my external SONY DVD RW DRU-720A , before I
can flash the new firmware. But how can I tell which IDE channel , in device
manager controls my SONY DVD RW DRU-720A ? I also have both a internal CD-RW
drive , and a internal DVD-Rom drive . And a external USB Seagate hard drive
.. And my controllers are IDE ATA/ATAPI controllers .
I will very much appreciate someone telling how to "sort out" which DMA
setting goes to my SONY DVD RW DRU-720A .

IDE channels are only internal hard drive connections. USB drives do
not have the IDE setting for DMA.

I didn't know that . Then what is the relation between DMA and DVD
drives ?

DMA is an advance access method to allow faster disk access. It is
for mainly any internal hard drive, DVD / CD or any drive that uses
the IDE / EIDE / ATAPI interface. You need to use a Ultra DMA IDE
cable (40 pin 80 wire) data cable.

The warning is a general warning for updating most firmwares via IDE
channels.

Just make sure you are using the correct firmware updater for your
drive.
