-A part of the lead-in, the entire first pregap and a piece of the first track, index 1, is dumped.
-Then use the first sectors of the normal dump to search them in the dumped file, find the portion which matches those first sectors and extract the previous 352800 bytes into a separated file.
-The subcode is easy, just extract into a separarated file the frames with 00:00:00 - 00:01:74 AMSF.
I confirmed PX-755SA, but didn't confirmed PX-W4824TA. Do you know which a plextor drive is supported?

PX-W4824TA (+98) doesn't support that at all, the range extracted this way is fully messed and the drive produces strange mechanical noises and halts frequently for a moment the dumping process.
Any +30 drive is fine, tested in my PX-W5224TA, PX-716AL and PX-755SA.

Tested the new function:

https://redump.info/disc/29165/
While works OK to be actually useful should work this way, without needing that the user specifies any special parameter:
-When ripped the subcode and the main channel, determinate if exist any TOC vs. subcode desyncs. If not so, proceed as usual and create the normal dump.
If exist these desyncs, then create automatically two versions and dats of the dump:
-With subcodes indexes in priority
-With TOC indexes in priority.

Any idea why it took like six hours to dump the disc from attached logs?
https://dl.dropboxusercontent.com/u/355 … l_logs.zip I tried an older version aswell. Same result. ISObuster did it like in 3 minutes or so, with the same result. I have soem more of these disc with the same problem.

I thought that the supermegaslow reading process due to packed mode for subcodes which doesn't like at all R-W filled with neither zeroes nor CD+G data was solved by changing to the raw mode (unaffected by this).

Coded it (and del /s option). Please test.

refixed.

Just (Subs indexes) instead of _SubSync .
The last frame of subcode isn't altered anymore, see the posted subcode.
