sarami, may I ask for a switch that will prevent filling SafeDisc and other error sectors with 0x55 when descrambling?

Why?

Because I want to examine the sector data, the C2 error is always in bit 312, I think this is like CDS and there is nothing "wrong" with the dumped data.

I am working on a SafeDisc unwrapper to remove it and I want to examine everything about it I can.

What would I check with cdtoimg when it cannot dump safedisc? I can post the sectors if you want to look at the output of my disc.

FatArnold has enountered the MSF bug on the linux build with safedisc in this thread, there is logs posted. http://forum.redump.org/post/71345/#p71345

Can you also make an option to reduce the read speed when encountering errors.

I am having a problem dumping Hegmonia - Legions of Iron, here are the logs. https://drive.google.com/open?id=1g54NB … seEeQ3qHzB

Looking at the data that was dumped, the first bad MSF sector has an ecc/edc error and the additional blocks the sync is shifted over in the blocks by 16 bytes, where the first 16 bytes are some random bytes or from the previous sector.

The disc dumps without issue in CloneCD and Alcohol.

Yep can confirm. Wasted money buying an Optiarc for that, but at least it can do the initial dump faster than the plextor can.

Yes very, when I see nonsense.

Because it's META DATA and has nothing to do with the title name. All this crap should be kept in a separate file, json or xml or something.

I don't care at all about your p2p sharing and "sets" as all that stuff is not at all important to this projects goals. If you can't organize files by region yourself, that's your issue and nothing to do with preservation.

So who's got suggestions then, metadata is needed, but I agree that filenames are sometimes ridiculous.

I personally never liked the languages or regions in the name, especially some releases with like a dozen languages. I simply rename everything on my end how I want and don't even bother with .dat since everything becomes an unsortable ugly mess mess. Granted that's my personal thing, but it doesn't correlate to the original point of the thread.

There is plenty that is DOS/Win95 and PC98 too, on the same disc. Amiga 1200/CD32 are also pretty much interchangeable too outside Akiko. Good thing we don't do floppies, or C64/128 and CP/M would be a mess as well.

This discussion has been going on forever, and now getting into Video and Audio stuff there needs to be something else defined, no intro doesn't cut it. Said that 10 years ago, it's true today. A lot of stuff it just not a tightly controlled closed source product that is easily put into a box.

One mod wants to do it one way, and another mod wants to do it another way, and we're still in the same place with pointless bickering instead of hammering out a solution that everyone can be happy with, or at least tolerate. DJ and I tried to bring some kind of consistency to PC, but that's been thrown to the wind again with all kinds of random whatever defining versions and we're split down the middle about editions being in the name or not.

Accuracy in filenames should be to identify a particular thing, not some OCD thing with perfect naming or caring about how long it is or whatever. It should have some kind of standard, and it cannot be based on information that not all discs have like the PVD date, or Version of the exe, or whatever other non universal thing, and it's only going to get worse with entertainment media. I'd just assume leave them out if they aren't directly tied to a title to function.

There's plenty of valid points from all sides, it's time to figure it out and stop avoiding it.

No intro is designed for console roms, it makes no sense for anything else. Period.

Thanks for fix. Actually I feel like I should thank you so much for making this tool, it has made dumping so much smoother to do and saved me countless errors and loads of time. You should start a patreon or something so we can donate to you.

As for the Yamaha it should if that's a standard command, I am able to change the speed with other tools fine.

The strange thing with dumping speed, I don't know, the disc does speed up but the time taken is the same. Some bottleneck?
I got Haldrie to test this too, same thing.

My drives have never been put in silent mode, they read fast when installing from them, and with any other tool. Perhaps this is why the set speed fails on my Yamaha CRW-F1, there is a bug in it. Tried 716SA, 760A, 5224 and 4824, all same behavior. All drives are able to rip discs with Alcohol or CloneCD at 40X, and Plextools and OptiDriveControl read tests are fine.

:EDIT:

Ripping audio discs with C2 and EAC is also fine.

Two things, when dumping Links 2001, which has SafeDisc I used;

DiscImageCreator.exe cd h "..\Track" 16 /d8 /c2 20 /s 2 /sf

After reading the whole disc, it went back and tried to re-read the SafeDisc sectors? Very strange behavior that I have no seen it do before and I've dumped quite many SafeDisc now with the same command line.

Also I've noticed that setting read speed to 8, 16, 24, 32, 40 makes no difference with CD dumps and it is always dumping at the same speed (about 4x?), but the disc is audibly spinning faster. DVD Dumps fast. I did not try without C2, but this should not make any differences as it doesn't slow down Plextools, OptiDriveControl or EAC. I asked some others to test that in the Discord.

OK so I bought 7290H5 to dump laserlock discs with it. The disc in question is this one http://redump.org/disc/12951/ , which when I originally dumped had too many errors and got marked red. Well I've been trying to dump this disc all day now with marginal success. I got the best dump using clone CD which took several hours and resulted in a dump with 972 errors instead of 1440 previous plextor dump or more than 10000 as with DIC.

I ended up finding the patent for laserlock and seeing how it works, and according to the patent document there are sections with extended "lands" on each side of the readable area between them, this is the "ring" you see. There are 5 "zones" on the discs, there is the 2 normal zones "1 and 2" which are the start and end of the discs. Then 2 more zones "2 and 3" which are these areas of extended "lands" and finally the protected zone "4" which is between the 2 and 3 zones. The protection check routine is supposed to use an angle to move the head or calculate the "good" area of the disc to be read, and this seems to hold true given my findings.

The interesting bit is the errors seem to follow a distinct pattern of a range of "bad" sectors which cannot be read, 1 sector which has no ECC/EDC data in it, and then a block of good sectors, and then rinse and repeat with the larger "good" zone between.

Now I have tried this tool with no positive results in recovering the "bad" sectors at all, not with 10 re-reads, 50 or even 1000. It fails always which leads me to believe that these sectors are indeed extended "lands" and are not readable by any means on any drive. I will attach the EccEdc check log of the dump which more clearly represents what I meant by the pattern, which is very obvious.

Yeah I thought it was dirty head too, but I cleaned it and still this issue. It seems to do this after running for a bit and dumping a few discs. Whereas I can dump hundreds with my other one and it's fine. I dunno...

Quality control seems to be an issue with later plextor's, I never had an issue with any drive until a I bought a new old stock 5224TA, it is having lots of weird problems reading PC CDs that my other plextors, including my other 5224A that I've had for over a decade can read just fine. Sometimes it works, sometimes not.

Neither my 716 nor 760 can read 1/2 my DVD games, I use my BenQ or LiteOn for those since plextor is nothing special here.

Setting drive speed is also easy to do with OptiDriveControl, I've used it for over a decade to set the speed with other tools that don't support it like IsoBuster.

It would indeed be nice if the tool had an option to do so.

I would like the iterative process to be automated as well, this shouldn't be too hard to accomplish by merging good sectors after dump, then running EccEdc and getting a new range, cleaning up a temp folder, and repeating with the new range until all are dumped or a threshold reached.

I think it may also help to perform seeks between re-read attempts after a re-read threshold is reached, I have used this method to dump problem sectors with ISOBuster by seeking sector 150 or some sector near the end of the disc and retrying.

Is it possible to defeat/dump the cache ala EAC? Perhaps this would also help.

I personally prefer the 5224A as it has no issues with any CD. I have a 716SA, a 760A and several other CD units. In my experience the DVD units are kind of duds with a lot of DVDs (and probably why Plextor went out of business) if you plan to dump DVDs too I would choose a better drive for that specifically and get one of the CD drives for CDs. The Vantec IDE to USB 2.0 and 3.0 adapters are both known to work and not very expensive.

I am unable to dump this disc because of a Q subchannel checksum being 0. The disc is fine and dumps fine with other tools.

Would you check it please.

possible mastering error from clonecd dump?

attached subs from clonecd.

You can also already sort by most recently modified.

I am not interested in any console stuff at all, or stuff with foreign languages, the main page doesn't bother me regardless.

Just open multiple tabs with each console you are interested in, bookmark it. You can then sort by most recently modified when loading the page.

I would prefer ir0b0t spend time doing things that need to be added to the site rather than convenience things people can do on their own.

OK, please disregard the weak sector comments about SafeDISC for now. I had these 2 discs buffed and they now read correctly despite not having any visual defects before hand. So could you revert what you did there, and also restore the hashing until a command line version of RapidCRC is made by someone. Thank you.

sarami do you still have the build you posted on the 12th of may or so, with the removed hashing updates to console.
