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 .
