Somehow you got the old hashes that are missing the L1 video. I thought FreeCell supported XGD2 discs, but maybe it got broken in a newer version. hmm

If L1 video area isn't zero, I think it's a bug of ss_sector_range, not FreeCell.

@user7
I uploaded the latest DIC (20180614). I supported XBOX/XBOX 360 (except XGD3) in this version. If you are interested in newest version, plz test and report.

There's no problem in my pc.
Does this occur with only [PSX] RC Revenge? or PX-760?

This option would be extremely helpful for dumping old hard CD-Rs.

Without /c2, it reads until the end.

The problem is that DIC was spitting out no C2 errors when some of the dumps were clearly bad...

It's possible that it's the bug of DIC, but I can't judge whether they're clearly bad or not without logs.
DIC merely uses the c2 error bits returned by the drive. I say several times, but c2 error handling of the drive can't completely be trusted, so I recommend using the disc of good condition as possible not to put the burden to the drive.

ok, cp-talk is difficult for me, but I understood the swap command of dic is effective when reads huge lead-out.

swap
---
1. Insert the audio trap disc to a supported drive.
:
:
6. When dumping finished, the drive tray open automatically.
7. The drive tray close automatically after 3000 msec.
8. Read TOC and img is descrambled automatically.

and I may add below.
9. If option(/74) is specified, reads lead-out till the specified time.

Btw, does subdump uses crc6 to fix subR-W of CD+G?

I have worry about spreading the c2 existing image.

If this is really data of the ring, does burned cd-r with this data works in sega saturn without hacking?

Maybe they mean the multisessional discs?

Maybe so.

All the sectors after the user area are marked as 0xAA in the subs and are either empty data or empty audio sectors, they go upto the very end of the disc

Even if it is so, it is enough in 90 sec to preserve lead-out. If there are some data except empty and shifted data in lead-out, it's not already lead-out.
Saturn ring, I don't know the detail. At least, this ring can't be read unless someone hacks sega saturn.

I checked multi-session disc.

plextor (0xd8)
lead-out of 1st session: all (6750 / 6750 sectors)
lead-in of 2nd session: part (6 /4500 sectors)
pregap of 1st track of 2nd session: part (137 / 150 sectors)

plextor (0xbe)
lead-out of 1st session: all (6750 / 6750 sectors)

Pregap/Lead-In sectors are read randomly, you can read the -5000...-1100 area a couple of times and get different sectors each time.

I understand reading is random, but even if reads the disc how many times, it is about 1900 that can get the sectors.

He preserves the last TOC iteration only (around 10-20 sectors) and the pregap.

We also need to determine how many sectors preserve because it is impossible to read all lead-in sectors.

READ_TOC(0x43) doesn't output the data area, though, only subs

Yes. It is valid if you permit not to preserve the main channel. (But I know you don't permit it.)

Lead-out sectors go upto the very end of the disc. If the main data area is small (a few megabytes), the lead-out would be 300 000+ sectors.

Yes Lead-out sectors/area exist upto the end of the disc, but acutually recorded data in the lead-out is 6750 (90 sec) + α sectors.

Why α?  http://www.itmedia.co.jp/news/0203/13/cdswhy_2.html

リードアウトは2分といわれていますが、実際の規格は1分36秒で、残りの24秒はマスター情報領域（PMCD）です。しかし、最近のドライブは1分36秒か、もっと短いものが増えている。

But

リードアウト領域には、90秒間の無音データが記録される。

https://astamuse.com/ja/published/JP/No/2001093150

第１セッションのリードアウト領域の長さは１分３０秒と定められている。

I don't know which of 90 sec and 96 sec is correct, but I know almost all drives can't read lead-out and Lite-on can read 6750 sectors.

I think it should work another way, I'll try to describe it in the DIC thread.

I think subdump's logic is better/best, but it takes subdump very long time to dump the sub, so I can't use it. (In the first place, I don't know the subdump's logic because this is not open-source.)

And I've asked to add an automatic 1st pregap and TOC reading into DIC already, but you haven't added that yet

I checked the lead-in/out and pregap of 1st track once more.

Plextor
lead-in: part (about 1900 sectors)
pregap: all (150 sectors)
lead-out: part (100 sectors)

Lite-on (LH-18Axx, LH-20Axx, DH-20Axx)
lead-in: no
pregap: part (142 sectors)
lead-out: all (6750 sectors)

----
About lead-in:
As I told you, the lead-in can read using READ_TOC(0x43). Not only plextor but all drives can preserve it as the raw binary file like xbox preserves SS.bin, PFI.bin and DMI.bin.

Jackal wrote:

it will still produce potentially bad dumps with missing data because there is no overread into lead-out?

Before dumping, dic checks if the drive can read lead-in/out or can't, so the combined offsets plus disc can't be dumped absolutely by BW-16D1HT.

DIC uses 0xd8(READ_CDDA) to detect the offsets if plextor is used, and uses 0xbe(READ_CD with CDDA flag) if non-plextor is used.
Almost all drives return error (Illegal Mode For This Track) if 0xbe with CDDA is used. But some drives returns the offsets properly (UH12NS30, BC-12D2HT) using 0xbe.

                VendorId: ASUS    
               ProductId: BW-16D1HT

Definitely, this drive can't dump the scrambled image if subcode flag is 0, so the offsets is incorrect.

Subcode flag 1 is ditto.

But if subcode flag 4 is used, this drive can dump the scrambled image and the offsets is correct.

I check the sector is really scrambled or not using msf and mode.

It would probably be better to block CD dumping (or add warnings) on drives without D8 (at least by default, without a special parameter)

I consider it.

Some fixed.

 /ms

It works now, but the lead-in of 2nd session can't read.
If /ms isn't used, dic skips reading 6750+4500+150=11400 sectors.
(6750 [1min30sec] is the lead-out of 1st session . 4500 [1min] is the lead-in of 2nd session. 150 [2sec] is the pregap of 1st track of 2nd session.)

Uploaded test version.
-added: support xbox security sector dumping (needs kreon's drive)

DiscImageCreator.exe xbox <driveletter> <filename>

@Admin or Moderator
Why xbox preserves the hash of Physical Format Information (PFI) and Manufacturing Information (DMI) in comments?
All DVD based disc (gc/wii, ps2 etc) have PFI and DMI but there isn't the hash in comments except xbox.

As long as a proper Plextor is used, will it make a difference if that flag is or isn't used?

No difference, but some ide-usb controller can't get the drive name, so user who uses such a controller needs this flag.

there are two BD drives listed under the CD (media). Can these models dump CDs correctly?

If you already have these drives, please try. If not so, try this http://forum.redump.org/post/60603/#p60603 using the drive you have now.

Solution 2

Added this, but still buggy, I think.

How to use

1. insert the audio trap disc to a supported drive.
2. run (stop spinning disc) -> DiscImageCreator.exe stop [DriveLetter]
3. use a pin to press the escape eject button, so the tray will eject (or remove the drive cover).
4. insert the disc and run -> DiscImageCreator.exe close [DriveLetter] or gently push the tray back (or put the drive cover back on).
5. run (start dumping scrambled img) -> DiscImageCreator.exe swap [DriveLetter] foo.bin [DriveSpeed(0-72)]
6. when dumping finished, the drive tray open automatically.
7. The drive tray close automatically after 10000 msec.
8. Read TOC and img is descrambled automatically.
