There are very few drives that can do that in a reliable way.
In short, you have to dump the LD area with the Plextor and the HD area with the other drive.
Please read guide linked in post above yours, it has some recommended drives (section "Dumping the HD area")

Keep in mind that even with the recommended drives process can be quite difficult, especially in discs with scratches and will take some more patience than dumping a normal CD ROM.

i just bought a PX-708UF for cheap and offcourse it had a dead laser.
I replaced it with a new one, and normal disk are being read fine,

Only when i try to dump the HD area, it takes forever with dcdumper.

I tried it on two discs (that have some scratches on them)
Anyone have an idea what it could be ?
Normal discs it reads fine !

Dumping on Dreamcast omits certain pregap sectors (only affects the discs with more than 1 track in HD area), also it seems the GD ripping tool doesn't recheck the dumped data, so you need to dump every disc multiple times to ensure its data consistency. Also, some of Dreamcast drives seem to be unsuitable for dumping (they produce weird errors in data and also have an unusual read offset).

Yes, this is abnormally many non-matches.
It *is* hard to match sections (with 1 and 40 being the worst), but normally at the second pass you should be getting at least 10-15 sessions matching with any good quality disc, potentially even more. And the entire disc matched within about 10 passes in most cases with disc in good condition.
We have seen cases with erratic behavior like that, where it proved better to stop and start the dumping from scratch. Ie eject disc, redo the trap disc and start again). As a rule of thumb, any dump that is going on for more than 1.30-2 hours, will never complete properly or will turn out bad even if matches found.
If your drive still behaves like that after some tries, adjusting the pot with help of a multimeter should be a last resort measure before declaring the drive bad.


Hello maddog thanks for the quick replay,
I have cleaned the laser and will try again,

I have one other question, what is the difference between dumping the disc on PC and on the dreamcast with GD ripper ?

I am just starting with trying to dump my dreamcast games.
Im using a PX-706A to dump the LD, and a SH-D162C to dump the HD part of the disk.

But I get a lot of non match, it has been trying for almost 10 hours now. and this is the log below.

Im I doing something wrong or is the laser bad ?

In the DIC thread it says it's a supported format, so is DIC better to dump than the methods in this thread?

Please advise as I have a Dreamcast collector friend that might be interested in helping. Thanks smile

If I'm understanding the guide on Wiki correctly I'm to do the following for method C:
Run CD Tool
Insert trap CD
Run startstop
Pin eject and replace with DC game
Make image with CD Tool as per specified settings.

Am I doing something wrong here? Is removing the cover a requirement for this drive?
