Try to use DVD model of plextor if you have.

That kind of sucks, the DVD drives are awful and unreliable

That's a shame, but thanks for the quick response. Unfortunately my dvd model stopped recognizing 99% of discs a while back. I tried anyway to no avail.

The only drives I have at the moment are a Premium (which is what that dump was) and an ASUS (which can't dump multisession either). So I guess I'll just have to pick up another dvd model to dump this.

I confirm the problem. I can't finish the dump of one multisession disc (with multiple audio tracks). On both PX760 and 4012...

I've found a problem with dumping some DVD-Video discs using DIC.  Well, really, 2 problems.

First, starting with DIC 20200203, all of the Cube DVDs fail to dump, with the error being "nLBA 262, Directory Record is invalid".  DIC 20200204 is also affected, while 20191116, 20191223, and 20200120 are not.  This immediately stops dumping right at the start, with a 0-byte image file.

Secondly, DIC 20191223 and 20200120 produce an error with Cube DVD 01.  Unfortunately, my disc is rather scratched and it was hard to get a full dump, so I can't do too much testing and most dump attempts are polluted with other errors later on, but I did get a clean dump with 20200120 (which is the one I submitted there).  The specific error appears at the start and is this:

LBA[702695, 0xab8e7]: [F:ReadDVDForFileSystem][L:855]
    Opcode: 0xa8
    ScsiStatus: 0x02 = CHECK_CONDITION
    SenseData Key-Asc-Ascq: 03-11-05 = MEDIUM_ERROR - L-EC UNCORRECTABLE ERROR

Dumping continues after the error, and (in that one lucky dump) I didn't get any other errors, including when it read that same area for actually writing.  (That area is all zeros, though).

These are all 8 cm DVDs, so perhaps that has something to do with it?  Unfortunately I don't have any regular full-size DVDs to compare with.

The first is probably a bigger issue since it completely prevents dumping these discs with current versions of DIC, but I am curious why the second one happens too.

Looks like both issues have been fixed!  Sorry about that; I assumed that since there weren't any more commits in the GitHub repo, there hadn't been any further changes, and didn't think to look for the test version.  (I was still unable to complete a dump of DVD 1, but that's expected due to the scratches on the disc, but it at least started).

I use it on Windows 7 64 bit Enterprise without an issue, and no, it's not an illegal version.

ok, BW-16D1HT was recognized from Bus Hound. As a result, my drive couldn't get the last sector +3, +4 etc.
But I added reading code until the last sector +10. http://www.mediafire.com/file/eq80y20l9 … st.7z/file
Test plz. I want to see these logs.

I dumped a +2352 offset disc with my ASUS using the new test build. Hashes don't match my plextor dump.

Last sector + 1 is good.
