ImgBurn BD-R writes perfectly, but max write speed is only .6x?

[ChuckT]

Not sure if this is to be expected: My XP system equipped with an older LG SATA BD-writer (see log) creates perfect BD-R copies every time using ImgBurn, but the maximum write speed is only 0.6x or .7x!  Shouldn't it be closer to the 2x or 4x advertised value? 

 

When I write BD-R discs using DVD Architect Pro 5.0, they write at a faster speed and report no errors, but the discs sometimes have data errors on them. That's why I'm using ImgBurn - RELIABLE!

 

Should I just live with the .6x max write speed, or is there some problem (cable, driver, drive?) I can fix?

 

A log file is attached.ImgBurn.log

 

Thanks for any suggestions. -ChuckT

Maybe the second FAQ:

Yeah, I'd go for 'Tools' -> 'Reset DMA' and then reboot.

 

I'd probably also crossflash to a GGW-H20L and then install the newer HL07 firmware.

Problem solved!  That channel was using PIO instead of DMA.  Write speed now at 4.1x and working great!

THANK YOU THANK YOU THANK YOU!

 

(If I just need to burn BD-Rs, I'll probably avoid the firmware update, since it is working well, unless there's some other benefit?)

I don't know the ins and outs of what the firmware updates do, but at the very least they'll add support for newer MIDs.

 

I'd hope for strategy tweaks (better quality burns) and general bug fixes too.
