Redump Forum

You could try Isobuster for dumping that DVD. When reports first error, select Replace with all zeroes. However, this will take hours to complete. To speed up things, low transfer retries to minimum: Options, Communication,  Read Settings.

For CDs, CloneCD, fast error skip enabled and a drive which can skip read errors fastly. Toshiba DVD-ROM drives, based on authentic Toshiba chipsets (-472 in Accuraterip), were the typical suggested readers for this purporse.

I gave up on the error skipping methods. They take too long and it usually gives me a different unreadable sector each time I try to copy. I was hoping that there would be an easy method to copy these discs, but I'm not too concerned about them, I was just curious if they could be dumped.

EDIT: I tried your IsoBuster method and it didn't work, the program just locked up with two different drives. I've already tried the CloneCD method, so it looks like these discs are copy-proof. It'd be nice if there were a program to run on the PS2 itself that could dump discs, that might be the only way.

Last option for these CDs is the intelligent bad sector scanner in CloneCD, or CDTool, retry error count to 1 and use a drive which can enable Transfer erroneus block (ECC off).

Is it possible to dump the CDs by audio trap disc, or is even reading as audio not possible?

These areas are either weak sectors or even not pre-formatted!

As for discs with those visible rings, they can not be dumped, both, CD and DVD.
You would have to mark the unreadable sectors somehow, and when burning
let the burner skip over them, custom burning software is needed for this task.

Weak CD sectors may be dumped in scrambled mode (which depends on your drive).

Final conclusion: skip these discs

I was already using the intelligent bad sector scanner with the SafeDisc profile.

Dumping as audio with the audio trap disc didn't get any farther than dumping as normal.

I agree with iR0b0t. Those rings look like physical gaps in the discs, which is causing the dumping problems. Even the blue disc has a ring, which is probably why they all stop at 6%.

Here's some info about the discs if anyone wanted to know:

CD discs: 318933 sectors, has data from SLUS-20202 (Crazy Taxi)
DVD discs: 2282416 sectors, has data from SLUS-20071 (DOA2: Hardcore)
