Could Sony AW-G170A crossflash to AD-7170A?

[qanda]This thread is about the Sony AW-G170A / DRU-170C. Click here to see full specs[/qanda]I use AW-G170A for couple years now and flash it to Liggy’s AW-G170A Bitsetting Firmware 1.75 with 1.20FF DVD R’s Strategies.
I burn the Verbatim Digital Movies DVD R 16x disc and Nero 6 Ultra Edition 's verification told me that

“Sector ***** on disc has different content to source”

I change to Ashampoo Burning Studio 8 to burn and verify then it told me that the disc is not compatible with the drive.

The disc is reading fine but i can’t check Disc quality with this drive.
I scan the disc for error with Nero CD-DVD Speed with file test and surface scan, the result show nothing wrong…

May this should be a problem with the firmware or the drive is not in good condition?

Can crossflash the drive to Liggy’s AD-7170A Bitsetting Firmware 1.05 with 1.21GF DVD R’s Strategies fix this problem?

thx for help and sorry for my poor English :stuck_out_tongue:
