I am posting here as I understand my SONY DVD RW DW-D22A is a rebadged Liteon SOHW-1633S ( and there is no Sony forum). I also understand that my DWD-22A is a OEm version of the Sony SONY DVD RW DRU-710A.
I would appreciate help on the following problem.
The dirve is about four months old and has been used for about 60-70 burns.
Started burning with very high error rate (per Kprobe2 test) even at 4X
Then would not read disk at all in Kprob2 and gave “Servo XXXX” error message. After a long wait, Kprobe2 will report information on the Drive Info inquiry.
NOW, will not detect or autorun any media
Tried to burn with Decryptor with “verify” after burn but got “could not establish link” error message
I have check the physical connections, jumper settings, etc.
Should I re flash the firmware. If so, cannot find F/W for the DWD-22a so can I safely use DRU-710A or Liteon software. Also, the troubleshooting guid says there is a Windows Firmware tool but I cannot find it.
Thanks for you help on any of the above questions.
