Makemkv uncorrectable error then rips1/31/2024 I was able to fix three discs that repeatedly failed due to uncorrectable errors, and I haven't seen this method posted before so I thought it's worth sharing.įirst of all, I did try the common troubleshooting steps (update MakeMKV, clean the discs multiple times, use Pledge/furniture polish). These are 2 disks out of around 230 Blu-Rays in my collection, none of the rest of which I have had a problem with in the 2010 LG drive (if the 2009 one hasn't liked them). My USB drive is a Pioneer BDR-XD05TB I bought in 2019. HL-DT-ST BDDVDRW CH10LS20 (LG branded 5.25" Blu-Ray burner drive circa 2010 - reads all but these 2 disks from my collection) HL-DT-ST DVDRWBD CT10N (LG branded slim-line BD-ROM/CD-burner drive from a Dell laptop circa 2009 - refuses to read any recent disks but happily rips anything from the same time) Both of the older drives are LG, the newer one Pioneer but I guess that age has more to do with it than the drive manufacturer. Age maybe a factor - the internal drives (which have issues) are older, the oldest refuses to read any disks manufactured in about the last 5 years (simply refuses to acknowledge there is a disk in the drive when one is inserted) but is fine with older disks. It really does seem that the drive might be the source of the problem in some cases. Since the first one had damage I assumed the disk was broken and beyond hope but when it happened again with my brand-new disk, which looked pristine, I became suspicious and tried ripping it with my external USB drive (instead of either of the internal ones I usually use) - and both disks worked first time with zero errors! Interestingly I've got 2 blu-rays, one with obvious physical damage (err.a scratch), one brand new and neither would not rip with "Scsi error - ILLEGAL REQUEST:ILLEGAL MODE FOR THIS TRACK" ( ) followed by "IO Error". I've mostly come across replicated DVDs that are silver and the occasional gold. It's not clear if replicated DVDs ever use disks that are purple. I didn't do an extensive search but a couple of sources state that duplicated DVDs - on-demand - are always DVD-R disks. The only other DVD drive that I have is a Blu-ray drive - a PS4 - which I'll have to test with an on-demand DVD but given your experience with your BD drive, I'm not sure if I'll have any success with playing the DVD. My LG DVD drive lists support for DVD-R and DVD+R disks too but for some reason, can't detect these on-demand DVD disks. I don't buy "on demand" disks anymore, if there is any alternative.ĭo you remember which one of your DVD drives was able to read the on-demand disk? Brand and model?īased on your information, I did some digging:Ī few sources state that all DVD-R and DVD+R disks are purple and are most likely to be compatible with old and new DVD drives. I finally had to get out one of my DVD drives to get a good copy. I've had one title that had I received 3 copies that failed in the exact same location, when read with a BD drive. has a disclaimer on such disks that they "may not work in all drives". none of the discs in these sets are detected by Windows 10 when loaded in my DVD drive The purple DVDs don't seem to have a lot of data or the purple coating makes the amount of data easier to spot (the data visually being the "dense collection of pitted rings").However, even purple DVDs without visible scratches aren't being detected. The purple DVDs seem to be a lot easier to scratch or the purple coating makes scratches easier to spot.With silver DVDs, this same setup can detect the DVDs.ĭoes anyone have any experience with these purple DVDs and understand what is happening? The DVD drive spins up and then after several minutes, spins down and Windows 10 doesn't report any disc in DVD drive in the File Manager. When one of these purple DVDs are inserted into my external DVD drive (read/write drive), my Windows 10 PC is unable to detect the DVD. I'm having problems with newly released DVDs that have purple coatings rather than the more common silver coatings.
