The next step I took was out of necessity rather than anything else, I am running out of HDD space so instead of copying over the BDMV folder to the location of the. My suspicion is that the drive didn't kick up a read error but instead gave garbage data (hence the ton of hash check errors in makemkv?), I kicked myself for not making a backup of the mapfile before I ran that last rescue.įor my linux machine I had actually installed ddrescue-gui so I ran that up with the intention of doing another rescue attempt (from the start), I noticed several presets in the settings.one of which reduced the block read size and was labelled 'best recovery' so I ran the disc up with that setting and the whole disc was rescued in just under 40m!?!?! (the previous rescue would take ~16hr). The isopropyl didnt seem to make any difference but I will still use it to clean any discs that I have trouble with later.

I ran through the remaining steps and unfortunately makemkv was still unable to rip the titles I needed from this one so I gave up temporarily.

OK TLDR: I succeeded in rescuing the disc!ĭdrescue zoomed through the remaining 1100 or so Kb on the last attempt a couple of days ago so I thought 'Wow!'.
