Yep, one in cue field and copied to comments iirc. Was adding it few days ago...

I have submitted one multi session coverdisk (Max Kids 2/2009)...

2019-07-29 18:23:52

Dump with /ms flag is the same as old dump. There's an additional info printed:

Have you considered adding automatically /ms flag when disc is multisession?

2019-07-29 13:31:50

sarami, have you looked more closely at multisession issue I reported few days ago? Sth doesn't look right there...

I have some multisession discs and I wanted to check those. I don't understand one thing. I made a DIC dump few months ago and got:

Now I redumped the disc with newest DIC from git and got:

First track in 2nd dump is bigger by 150 sectors, is it expected that old vs new dumps are different?

Mr Nexy: Problem with Plextor and 8x:

http://forum.redump.org/topic/13211/fir … or-drives/

"P.S.: If you own a Plextor drive which features the silent mode (for example: Premium, Premium 2 and PX-7xx drives [for this serie only the true ones, not the rebadged ones]), NEVER enable the silent mode. This funcion is somewhat buggy, and after of that your drive maybe remains stucked forever at 8x read speed for CD, even if you disable that mode."

All my drives are stucked at 8x. Shit happens?

2019-06-25 05:54:04

My Px760 starts reading DVDs when I disassemble it and clean the lens. As always is stops doing so after few weeks...

I have problems with safedisc 2.9 discs sometimes, it seems they have some type of weak sectors towards the end of the disc. They get no C2 errors, but get EDC/ECC errors after descramble and I have to manually redump those sectors many times in iso buster after performing a seek to 150 to get a good dump of them.
So far two discs have this problem, disc 3 of original Splinter Cell version, and Need for Speed Hot Pursuit. I wonder if anyone else has encountered this?
CSS seems OK now for the discs I tested.
If RapidCRC is not present with test version, hashes are not calculated. Maybe forget I suggested this as the tool has no command line version.
Can you remove the 4 spaces from produced dat files , I have to manually remove them always when submitting dump hashes.

http://redump.org/disc/46961/

I used to have problems with this disc. I think it uses weak sectors too. I had to manually zero out scm file in some places and then descramble manually to get correct data...

2019-05-12 19:15:24

+1

It slows the process a lot also on my PC.

An attempt to dump DPM data from SecuROM DVD has been documented here: http://forum.redump.org/topic/17084/ana … l-120-dpm/

2019-04-29 06:51:25

I tried going back, going forward, flushing cache, but it's all in vain...

Oh that's quite bad. Maybe eject + load (like hard reset) will make it work?
What happens when crc is 0 - some data is invalid?

2019-04-27 12:55:58

When subQ crc is 0 DIC stops. When I retried it worked. Is is possible to add some more complex restart logic? If crc is 0 go back 100 sectors and retry reading? This crc 0 thing looks quite random...

2019-04-25 20:35:06

Some of the dumps are here: http://forum.redump.org/topic/16655/ibm … to-redump/

TRUSTEDME + HARD groups. These are the suspicious ones that were picked up last time...

2019-04-25 20:04:08

Descramble algorithm: https://github.com/saramibreak/DiscImag … output.cpp

It's very complex...

Don't forget that even if you succeed at dumping few more sectors you'd still get unverified data. You don't have access to low level read commands that return DVD correction codes.

In CD terms it's like you would be trying to read more sectors from unreabable range but in 2048 mode. Your drive firmware tries to correct all mastering errors + data tracks defects which are in turn "masked" by ECC/EDC.

How can you be sure that the data you read is the data on the disc? Without correction codes it's not deterministic to dump such sectors.

Do you expect that people should rerip all those 2400 discs?
Maybe another dat should be created solely for those SS ranges (similar to DMI, PFI dats)?

I have DVD9 disc and DIC reports following data:

Why LayerZeroSector is different in both cases?

Hi sarami. I have a safedisc protected disc and I want to report some weird info. Below is a list of C2 error counters from protected range:
240
264
288
312

Each of these vary by 24. I can confirm that this is correct info.

2019-03-06 21:28:26

nightson: https://club.myce.com/t/difference-betw … eed/176851

Read about Plextor SpeedRead. But keep in mind that PlexTools is a true devil and better don't install it or your drive would go to shit...

2018-11-26 21:29:40

So if data / track hashes stay the same, what's the problem with emu devs, can't they just generate the cues internally on the fly?

2018-10-06 19:06:42

Wow, I forgot about this topic

If you're using version from 23th reply in this thread specify cue path as last argument!

2018-09-29 14:51:40

This example shows the power of DIC + Plextor drives

2018-09-25 20:31:37

00 FF FF FF FF FF FF FF FF FF FF 00 01 82 00 61

When you XOR with 0x60 you get 1 = Mode 1. It makes sense.
All other sectors are mode 2?

2018-09-24 17:36:14

Ok ^-^
