Optical Quantum 50GB 6X BD-R DL 25 Packs Spindle Logo Top Disc Model OQBDRDL06LT-25

Pros: So after my initial review where I lambasted these as utter garbage, I am happy to say that updating the firmware on 1, just 1 of my drives, has made these disc no longer fail. My BH14NS40 had a firmware update that was dated within a month. I decided to grab it, and now these discs burned 100%, and pass all verify tests with no errors at all.

So in conclusion, it appears that new firmwares need to be released for these discs for them to be used properly. My second burner, will still not burn these at all. But it is a much older burner, but it is still on the approved list with the "approved" firmware.

Cons: It sucks that I had to go through so many expensive coasters and wait for an updated firmware before these discs would actually work. I am extremely frustrated that the official website is WRONG about what firmwares properly support these discs.

Other Thoughts: Please check to see if you have a new firmware within the last few months before you buy these. If your drive mfg has not released a new firmware with new media codes, then do not buy these at all as they will be a waste of money for you.

It is highly possible that you may have to buy a new burner before you can use these dual layers properly.

Pros: None.

Cons: Total, abject garbage. Success rate below 20% and falling. Worthless junk.

Other Thoughts: Newegg needs to prominently mark these FMS discs as JUNK THAT WILL PROBABLY NOT WORK FOR YOU, before more people throw away the better part of $100 on this worthless garbage.

Pros: Well they were cheap, and the spindle showed up with no damage at all.

Cons: I really wanted to like these, honestly. I use the single layer all the time, and have no issues whatsoever with either of my bluray burners. Unfortunately, I am 15 for 15 for coasters. The discs either refuse to close, or have hundreds of verify errors.

I am using a HL-DT-ST BD-RE BH12LS35 1.01 and a HL-DT-ST BD-RE BH14NS40 1.00. Both of these drives and their firmwares are on the list on the optical quantum website, yet neither drive can burn one of these discs properly.

Nothing better than trying to make a disc, and you have to reboot your computer because imgburn can't close the disc at all, and after an hour of it attempting to close it you just give up.

I am extremely unhappy with these. These are almost as bad as the memorex discs that erased after several weeks, and the first generation of LTH discs that erased themselves as well. OH wait, those discs actually were able to be burned.

Pros: This is my second 25 pack...only had 1 burn failure because of " bad media"..... product shipped immediately and I am pleased with it.

Cons: None

Pros: Worked Perfect

Cons: None Yet

Pros: Best deal on the web I could find

Cons: So far with 4 discs, I have a 50% coaster rate. In both cases the burn was successful with a new disc.

Other Thoughts: Don't think the problem was software.

Pros: I have had no problems with these disks. I use a Lg BH14NS40 burner and have had no coasters on any type media I tried.

Cons: None

Other Thoughts: Will burn 3-D movies with perfect playback.

Pros: Excellent product! Burns with no errors.

Cons: Expensive.....lol

Pros: Outstanding quality no coasters.

Cons: Too bad newegg canot read they even sent these to another state!!!!!!! But not to me. Twice!!!!!+++++

Pros: These things are freakin fantastic! I've been buying the 25gig for over a year now, i've used hundreds of discs and rarely ever run across a coaster. That same quality has been implimented into the 50gig dual layered discs. All i can say is: well done Optical Quantum, your product is excellant.

Cons: None
