abalian Posted September 19, 2014 Share Posted September 19, 2014 (edited) Hello, I just started experimenting with blank Blu-Ray media, results not as bad as I expected. I have found no problems with BD-R SL and DL from Verbatim. Burned about 50 successfully so far. I started to try BD-RE yesterday. Results have been different from all 5 discs. Only one performed perfectly. The logs for each are attached. Disc 1 and 2 (zeroing sectors retries, no write errors) played fine on my standalone player. Disc 3 also, as expected since it showed no problems. Disc 4 will not play (Zeroing sectors retries, and writing errors/retries). Disc 5 behaved the same way as Disc 4 so I cancelled halfway. I noticed most errors are around the layer break, no errors at the start or end of the sectors. Does my drive dislike the media? Or is the media simply bad? They're repackaged discs, but seemed to be packaged fine. After Disc 2, I started wiping them very well before putting them in the drive. What can I do with Disc 4 and 5? Simply try again with same settings? If these discs are going to cause problems, should I just ask the seller for an exchange? Surely he has others I can try, hopefully some genuine VERBAT-IM ones. Thank you! Disc 1.txt Disc 2.txt Disc 3.txt Disc 4.txt Disc 5.txt Edited September 19, 2014 by abalian Link to comment Share on other sites More sharing options...
abalian Posted September 20, 2014 Author Share Posted September 20, 2014 (edited) UPDATE ------------ I did a full erase of Disc 5 and showed only four zeroing sectors errors. No write errors just like Disc 1 and 2. Playing fine now. Same results with Disc 4, but only ONE instance of failed sectors. No write errors. Disc 2 stopped playing at a certain point on my standalone. I skipped a few seconds ahead where it had stopped and the rest played fine. I'm so confused. I thought failed zeroed sectors were ok as long as the write process was successful and without errors. It seems not. Will I get more problems in the future? Every time I wipe the discs, I get less errors. Maybe it's a coincidence. Do these discs/dye need "warming up" or "breaking in" until they work perfectly or something? Should I take advantage of the return policy and exchange the discs that showed errors? I'm really hoping someone can shed some light on this! TIA!

LIGHTNING UK! Posted September 20, 2014 Share Posted September 20, 2014 The zeroing stage is just another 'write' operation really. I actually found it weird that you'd get errors during zeroing and then not get them during the actual write! Yes, maybe things will improve the more you try to burn the discs. As you've had problems with a large percentage of the discs you purchased, I don't think it's really worth trying more discs. Link to comment Share on other sites More sharing options...
dbminter Posted September 20, 2014 Share Posted September 20, 2014 I've only had experience with BD-RE DL from TDK. I formatted them and wrote data to both layers on all 10 fine in my Pioneer burner. Verbatim switched their manufacturing process for its BD-RE. They used to make their own which were very good. Then, they switched to CMC Magnetics, the WORST optical disc manufacturer out there. My 10 discs formatted fine and have written data to most of the available space on a few of them. I still wouldn't trust CMC media. Even though they apparently made a decent DVD+R, they made terrible DVD-R for Optodisc, how I first learned of their evil. I've got some TDK BD-RE SL's shipping to me right now. I will try to remember to report my findings here. Link to comment Share on other sites More sharing options...
abalian Posted September 21, 2014 Author Share Posted September 21, 2014 Thank you both. LIGHTNING you were right, I'm getting less and less zeroing sectors retries every time I perform a full format. Disc 1 zero-ed with no failures yesterday. dbminter, my Verbatim BD-R SLs are made by CMC! I was hoping I wouldn't hear that. I've had no problem with the 15-20 burned so far, but now I won't be surprised if I do with any of the rest. Cheers! Link to comment Share on other sites More sharing options...
dbminter Posted September 21, 2014 Share Posted September 21, 2014 Well, it could be a case that the CMC BD-RE's are actually decent media, like CMC DVD+R. However, I wouldn't trust CMC as far as I can throw their corporate headquarters building! So, I have 10 CMC BD-RE's but I'll only write to them as a last resort. I have some TDK's on the way. I have some TDK BD-RE DL's that seem to be okay. I lost about a $1,000 because of CMC! Optodisc used to make a great DVD-R and then they switched to CMC. I'd never heard of CMC before the forums for a certain other application. Once someone there mentioned the evils of CMC causing bad burns I checked my Optodiscs which were causing me problems. Sure enough, they were all CMC's! I spent about $500 in media back when it cost like $2.50 for a DVD-R from Optodisc and I also replaced my Panasonic DVD video recorder trying to troubleshoot the problem.

dbminter Posted September 24, 2014 Share Posted September 24, 2014 Well, TDK also sold out to CMC shit! These Japanese made BD-RE SL's I just got are also CMC I'd send them back but I can use them because they're inkjet printable. But I know from now on only to get the BD-RE DL's from TDK.

abalian Posted October 3, 2014 Author Share Posted October 3, 2014 That sucks! MIDs should really be specified by all vendors and sellers... Hope you don't get too much trouble with them. But yes, TDK BD-RE DLs are reliable. After successfully zeroing sectors on all 5 of mine without failures, overwrites are performing perfectly and at full speed. The only problem is sometimes, my Sony BDP-S5100 skips for some reason on certain burns, but once I eject and put it back in, and play the same area, it doesn't happen again... Both times it happened, subtitles were on although I doubt that's it. Link to comment Share on other sites More sharing options...
