Dumping DVDs RAW - An ongoing investigation (we need your help!)

[MrPepka]

TSST TS-L632H doesn't support or what happens?

Try again? Maybe the drive doesn't like the disc and can't read it.

The same. I tried with 2 different discs, the drive reads them correctly

BTW, if for whatever reason it seems like its way too slow (like 3+ hours) or seems like it stalled, feel free to stop it by using Ctrl+C and upload what you have. Some drives just don't like being bruteforced to that high value. I could probably restrain the values it's bruteforcing with but you never know if a vendor might be sneaky and put something at 3C FF FF or something, lol.

Here you go. I will try with another DVD later.

It has finished, here it is. The dumped disc is Earth 2160.

Not sure what to say...the drive just doesn't like it..

Generally, when it comes to TS-L632H (or SN-S082H, it's the same construction), in addition to the log, this file is also created

Disc: Split/Second (Argentina) (En,Fr,De,Es,It).
Drive: Plextor PX-755A.

I'm not sure whether to trust when the left most byte is different because other bytes within the page might be altered randomly from different runs too. I'm making notes of when this happens in the notes field but I'm looking for when the first 4 bytes are exactly 00 03 00 00 to know that it's workable for sure.

Fair enough, the point I was trying to make was, it may be a good idea to ask the dumper to try again with a different disc, since in his case this only occurred with one specific PC game disc.

Anyway, 6 more drives from me and a few friends, sorted in folders with which disc was used and all.  The _pylinux folder contains the modified version for Linux that jason098 and I did.  smartctl was used to get some drive info, so I ended up making it a part of the script.  So, some folders will have a smartctl.txt file with that info separately from an earlier version, and others will have that info included in logfile.log.

Thanks!!! Keep them coming!!!

That GU90N is really strange. So there are two versions of the GU90N, one is a DVDRAM drive and the other a DVDRW drive? Because both drives gave wildly different results, as if the firmware is completely different for both.

[Edness]

Yeah, I thought that was pretty unusual as well.  Perhaps another field is needed, denoting the exact "full" drive model/type that sits between the vendor and model names.  Or maybe just including that as part of the model name.  I dunno.

Here's 11 more drives.  One seems to be a duplicate on the spreadsheet, and another didn't return anything from any command.
(There also seem to be a few others at the end of Page 1 that were missed, FYI)

Thanks! Keep them coming lol.
