New dreamcast dumping program (test please)

[jamjam]

New version (0.42a)

Code: Select all

20110919 (0.42a)
+FIX:Read errors apparent since 0.3a
+FIX:Writing hashes to file

Have tested and found dumps to match in 0.42a which didn't in 0.41a. There may still be errors in dumping, lets hope everyone had the same problem as me 

The next version should just be for new functions, or more read fixes if necessary. Next version doesn't create/open the log file unless something will be written. Other possibilities I'm considering:

• Send stop start  commands to drive when there are many adjacent read errors (exiting program, doing this then running program seems to kickstart it sometimes, could just be waiting awhile or some other factor though)
• Specify 1x read speed (currently not, although sptd does seem to go a lot slower naturally)
• Suggestions?

Fair enough about ice numbers in brackets not being definite errors and just edc/ecc checks. Knowing that, I see why the ice log that made me think of validating by ice is wrong (because the input was wrong). Each section was (0.3a-0.41a) filled with the first 26 sectors of the section, so the audio tracks after a data track had thousands of ice errors as they were actually repeated mode1 sectors from the data track. My testing of 0.3a-0.41a must only have gone so far as checking the ice log, of what happened to be single track games, oops. A complete garbage dump but it would have compressed well 

Thank you all for testing, information and suggestions. Keep it coming.

Will test, first good game no scratches, second a bad one that has been cleaned

It seems to work now, at least i can notice it reads from the drive 

The main problem remains though, reading the last outer edge sectors, where drives have the most problems with, and setting the read speed down will not solve this issue!

Anyway, the real benefit is you have not to wait for the drive now till it fails to try a new attempt!

Don't see what you can improve now, the only real solution would be to hack the firmware and let the motor drive an other route!!!

Dreamon Volume 16 (Europe) (En,Fr,De,Es) - SH-D162D

Everything worked perfectly on this un-dumped by me disc. I have 3 copies of this, and had never dumped this.

Matched database.

Worked much better, no read errors, process was complete at the end of the second pass.

Now to resume one of my undumped scratched discs, and see if it dumps missing sections, i hope so.

[jamjam]

Here's the logs of some successful reads (matching redump), to show what I've seen using 0.42a with a "TSSTcorp DVD-ROM SH-D162C".
Observations:

• Retrying coupled with fake reads seems to work in many cases
• Step back doesn't seem to help much, may set the default to false next time unless others have positive results
• Persistence pays off. The fourth and 12th successful read of 446261-549150  for house of the dead 2 matched, and the resulting track matched redump

tossEAC if you're resuming from a dump made with 0.3a-0.41a, just delete and restart, what was dumped is likely junk. Also, can you retry dumping this please? Mine matches except for the last track, which has an md5 hash of d564c50937f50a051038b0e62a8bb1f4.

Creating dense.bin: Done. Pass this to ice.exe

Ill try that, in the next few minutes.

Trying now, plus i have two copies and both are mint, 100% clean. So what ring is on your disc, mine are both the same.

Section 1-49 initial dumped all ok.

Finished dumping CoolBoarders.

Got a match with jamjam's last track using his dcdumper, after extracting dense bin.

Then I removed a section of the dumped parts, but not the hashes (enough removed to entirely dump the last data track, we had the miss match on). All tarcks matched the hash's. Dense bin was created again.

Then I dumped the same section as i redumped, with cdrwin, the same section was then joined to the rest and ice exe found 1 extra error, this made the last track not match the database or what we should have got.

So then I dumped the other disc from beggining to end with cdrwin, and that extracted with ice normally and matched the dump made with jamjam programme.

Concluding the dump in the database (mine) is wrong.

On my defense, I do remember this being one of my first dreamcast dumps for redump, and im not sure if ice exe reported errors in the early days.

Ill post the full dump info when I post my dreamcast verifications and any new dumps, soon.

Outstanding work, jamjam!

First of all, thanks a lot for implementing DeviceIO. The new versions (0.3a+) do work for me, even on my IDE to USB adapter I've just finished my first GD-ROM dump using DCdumper (0.42a). 0.41a gave me a wrong last track even when using -i26. The 0.42a dump however matches the DB perfectly! I'm gonna submit it soon.

I have no idea if this has already been suggested, but would it be possible to put all the first pass checksums into a single file? When I dumped a disc using -i26, I had to CTRL+C it due to read errors, and I ended up with like 36.000 individual files It took my computer several minutes to delete these.

Apart from that, I couldn't really find any flaws with DCdumper yet. DC dumping is almost too easy now And yes, persistence does pay off:

Stupid first sectors, always giving me trouble!

[tossEAC]

Fake a read from 50000 with cdrwin then run DCDumper, works for me every time.

[jamjam]

@tossEAC
That's a relief, I'm still trying to dump mine with CDRwin as it doesn't want to play nice
Ring is "T-36901M-0145 MT B01"

@amarok
Thinking about it, if you used a cut-off sector with 0.3a-0.41a, it would produce a bad dump even if you used -i26. Those versions are toxic.

Putting all first checksums into an initial file would be annoying to implement given how it works now. How about the threshold for the interval increases instead? A minimum interval of 260 sectors would produce a maximum of 1940 hash files, less if a cut-off is used. Will keep the program flexible (~0.6MB per section is small enough for those tricky discs imo), and minimise undesired behaviour.

[amarok]

Ah, I see. Well, I'm using 500 sectors per section for now, so it's not that big a problem anymore.

But I've already got another idea Could you make section size variable? I mean, imagine I'm trying to dump a disc using sections of 500 sectors each, which fails repeatedly. Dumping the same range with sections of 250 (or 100, or 50, ...) blocks each however works fine. Would it be possible to tell the program to automatically switch to a lower section size once it reaches a certain number of mismatches? For example, if I try to dump a disc with -p50 -i500, I want the program to continue with, say, -i100 once the 50 passes are over instead of just aborting the whole process.

Well, thinking about it, that sounds even more difficult to implement

EDIT: Okay, forget it This idea is crap; I could just use the smaller section size to begin with Meh, sleep deprivation ftl
