I think both discs are no problem as mastering error sectors. Hereafter, admin or moderator judge it.

Surprisingly, it's correct.

FYI: I have tested a combined plus offset disc with mastering error on Asus BW-16D1HT and the result is the same as on Plextor 760. Probably more tests are needed but it seems like this Asus drive is finally a good replacement drive for all these retro Plextor drives...

EDIT:

Sarami I have such disc:

Code: Select all

     Combined Offset(Byte)     24, (Samples)     6
    -   Drive Offset(Byte)     24, (Samples)     6
    ----------------------------------------------
           CD Offset(Byte)      0, (Samples)     0

ASUS gave me wrong image. Last 6 samples of image are all zeroes. They should contain some data. Can you fix this?

EDIT2:

Reripped the disc and it was ok next time. I noticed that when there's more than one lead-out sector in cache it's ok. Maybe the computations are off by one somewhere?

I also tried it with the same combined offset disc using the latest test version (20201115T172518) and it was no problem...

Another one. Offset +1617 and 3 or 4 lead-out sectors - last 3 sectors were off by one (MSF).

I think something bad happens when there's not enough lead-out (aa) sectors in the cache. Maybe retry cache read by reading more sectors? I have dumped maybe 20 plus offset discs and had these 2 cases. Both had very few 'lead-out' sectors printed to console. This looks like a problem with drive cache...

How few sectors?
1 - NG?
2 - NG?
3 - NG?
4 - NG?
5 - NG?

It turns out it doesn't depend on number of lead out sectors. But in most cases last few samples are wrong. I'll try to dump the cache to disk and manually inspect what's causing this...

The 'main error' i was experiencing on CDi discs is not related to mastering, but drive model.

My 760SA dumps incorrectly: https://drive.google.com/file/d/15qbtq_ … sp=sharing
My 716A dumps correctly: https://drive.google.com/file/d/12bHisL … sp=sharing

For reference in Main Error, the 760 looks like this:

Code: Select all

LBA[017306, 0x0439a]: Track[01]: Invalid sync. Skip descrambling
========== LBA[017306, 0x0439a]: Main Channel ==========
...

But...

Jigsaw still has Main Error with 716...

IsoBuster also has issues with Jigsaw, so I think that one is a mastering issue.
