Question

The program copies a disc without the /c2 option very slowly when using the BW-16D1HT drive

Describe the bug
When I rip a disc in the BW-16D1HT drive without the /c2 option, the ripping process is very slow, the drive then switches to 8x speed. I tried changing the ripping speed, but the program ignores this setting. It doesn't matter which disc I try to rip this way, they all behave the same. BW-16D1HT firmware error?

/c2 is used, subchannel uses raw mode (001b) by DIC. /c2 is not used, subchannel uses pack mode (100b) by DIC.

It seems BW-16D1HT does not support pack mode. Therefore subchannel is fixed per sector and ripping speed goes to slow.

Meh. This means that the firmware needs to be modified to make the drive copy the disc faster without /c2. Okay, I'll get tired somehow, thanks for the explanation

No. If /c2 is not used, raw mode can be used, not pack mode.

How to use raw mode when /c2 is not used? Should I use the /be raw? command?

Should I use the /be raw?

Yes, but it didn't work as I expected. Fixed it.

Thanks, it works as it should

I reopen it, because it doesn't work as it should. To clarify: I do not use the /c2 option and even though I used the /be raw option, DIC heavily uses Pack mode

cd G:\ LPM2000.bin 72

It seems that /be is not used.

DIC not detecting the /be raw command was an MPF error, so I bypassed this frontend and ran DIC directly in CMD. Well, this /be raw command doesn't work as it should

/be raw command doesn't work as it should

Fixed it. And with /be, it will set raw with or without /c2.
