No scrambled data. Perhaps PX-760A doesn't support swap trick.

volume space size is 0x265b. It's 9819 sectors. 9819 * 2048 = 20109312 bytes.

It's easy to use volume space size instead of TOC, but I'm not sure volume space size is correct disc size.

Yes, the space used by all files as seen in Windows Explorer is indeed 20109312 bytes.

So, I guess I'm out of luck, unless I can find another drive that supports swap trick.

sarami, im still redumping my ps4 bd-r's with the new dic build. A few of the redumps match the isobuster dump, here's an example: https://drive.google.com/file/d/13xTymU … sp=sharing

I wanted to share these logs to match in case they are useful for study.

I'm testing dumping with a Plextor PX-708A using the 20191223 release of DiscImageCreator. I'm able to dump a Sega Saturn disc correctly in Windows, but I get the below errors in Linux using the same parameters. I have the same issue with the 20191116 release.

Hello,

I am having problems dumping some Japanese Dreamcast games. I got a px-708a drive with firmware 1.04. If I insert the Dreamcast disk it gets recognized as audio and DIC sees it.

When I want to dump it I get an error that I am not on the latest firmware.

So I update to 1.12, but now it not recognize the disk, it just keeps spinning. If I install 1.04 again
It will see the disk but get the error again.

Is there a command to skip the firmware check ?

That fixed it. Thanks.
But why does DIC require root privileges?

Seen quite a lot of dumps recently with incorrect gaps due to first sector is EAN. You need to implement a better gap detection logic: when the EAN or ISRC sector is detected and its P-channel is 0x00, you need to check the next sector's P and Q channels: if the Q-channel's track number is increased and the P-channel is filled with 0xFF, then the EAN/ISRC sector belongs to the next track.

Many SCSI commands require it.

No command, but you can remove this check from the sources and recompile.

/viewtopic.php?p=25410#p25410 - or try this build (3 months old, but I don't remember any DC-related changes recently).
