Never had THAT happen before!

[dbminter]

In the entire 26 years I've been burning optical discs, I've NEVER had happen what happened last night!

 

It started earlier in the day when I inserted a BD-RE into my drive and it made a loud grinding noise trying to read it.  The drive never did anything else out of the ordinary until a few hours later.  I was reading some data from a BD-R I had just burned to verify the contents when it suddenly made an even louder grinding noise than before and stopped reading the disc.  I discovered what had happened: the BD-R had broken up into 3 separate pieces INSIDE the drive!

 

Needless to say, I replaced the drive in question with one in reserve and I've had nothing untoward since.

Something similar happened to me last year. I was trying to read a disc using an Asus BW-16D1HT but I was getting some errors, so I tried opening and closing the tray every time the drive got stuck reading it. I did that about 5 or 6 times, when I took the disc out the last time, it was cracked from the center to almost the edge. I had no idea Bluray discs were so fragile or that the drive could damage a disc like that and I've been burning/reading discs probably as long as you have.

Mine occurred in an LG WH16NS60.

It's basically the same drive, right? I think the WH16NS60 can be crossflashed to the BW-16D1HT.

[dbminter]

I've not heard the two drives are compatible.  Particularly considering ALL of the firmware except 3.11 for the BW-16D1HT has been problematic and the WH16NS60 has been (relatively) bork free firmware wise.

You cross-flash it into a LG JB8 model and then cross-flash it again into the BW-16D1HT.

[dbminter]

I still don't see why you'd want to cross flash the "perfectly" working NS60 to the ASUS firmware that only ever worked with 3.11.

I was just pointing out the similar hardware, which is probably the reason why they are able to "break" discs.

[dbminter]

OIC.  You were making a comparison because both drives broke discs.  Well, I don't think it's because they're similar hardware.  Why would ASUS and LG share hardware with each other?  I have seen Verbatim drives that were actually Pioneers, but I don't think there's an equation there.

Hello! Been some time since I've wrote on ImgBurn's forum. Seen this post here and came up with a few possibilities.

First, according to my knowledge discs are made to support a certain reading speed: X1, X2, X4 and so on. Each one of them being a certain data-rate value:
-on DVD 1X equals (1385000 bytes per second)
-on CD 1X equals (153600 bytes per second)
(DVD being a bit over 9 times greater)
what causes this difference is pitch density and rotations per minute. Once the driver identifies what kind of disc it's reading, it should set limits in rotations per minute according to their rated standard, which is set as default in the driver's firmware.
(the rated standard is usually stamped on the disc itself, but the user can modify the reading/writting speed on PC through software)
 

Now here's where issues arise. Not all discs are born equal, same goes for every single piece of hardware coming out of the factories.
12 centimeter discs are made to keep their form as much as possible at a rated rpm (rotations per minute), if the disc is by any chance faulty from factory, degraded by time/environment or usage, it will warp enough for data to be unreadable at it's rated reading speed or even crack/break apart due to centrifugal force inside the drive.
This standard of disc format we are using today is rated to "stay in one piece" at up to ~23.000 rpm, but once a disc gets anywhere near that, it will warp enough to be unusable even if it does not break apart right then and there.

I believe your issue deserves to be studied more, and maybe test it out with a CD, DVD or even a miniDVD if you have any at hand.
(although a miniDVD will resist better at a higher rpm than 12 centimeter disc due to it's reduced mass)
