I’ve always been able to change the bitsetting of my Vebatim DVD+R DL to DVD-ROM with no problems.
Recently however, I caved and bought Imation DVD+R DLs as the store had sold out on Verbatims.
When using Imgburn to change the booktype, I met with the following error: “Failed! Invalid Field in CDB”
I tried 2 ways:
Change For: Current Media (For DVD+RW Media)
Current Setting: DVD+R DL
New Setting: DVD-ROM
Hitting change would get me the above mentioned error.
Change For: Drive (For DVD+R DL Media)
Current Setting: Unknown (FAILED!) Reason: Invalid Field in CDB
New Setting: Greyed out
My first instinct was to blame the quality of the discs, however I didn’t want to make a wasted trip to the store, let alone make a complaint regarding booktype settings which would be difficult for a typical salesman to understand.
Upon further investigation, I found that if I used the NEC tab of the Book Type, I was able to change for "Drive (For DVD+R DL Media) to New Setting: “DVD-ROM”
I also tried changing the bitsetting with a Lite-On utility called “LiteON Bit Setting Utility v1.3.5”
The “Change Booktype to” option is greyed out with error message “F/W not support!”
What would you suggest is my best course of action?
Is the firmware an issue? Perhaps a custom firmware would fix this?
I am using ATAPI iHAS324 Y BL1W
