    Yeah, no worries. That drive is a few years old now anyway. Probably a good excuse to replace it! How is your BU40N going? Is it working for UHD's?

    I know he's not going to do this method (we discussed it earlier), but, I would add something to this....it's likely the calibration data on that drive is corrupt. There are a couple firmwares for his drive out there where czar2mary created a custom firmware for other people with his extracted calibration data. The eeprom data mover with that firmware would copy the encryption data and leave his calibration data in place and probably fix the drive. Just an FYI for any future situations like this....it's a decent idea to just use calibration data from another drive with the digital signature of the drive being flashed.

    D'D's
    Have none to test with but reading and ripping DVD's and Blu-ray's work fine. Will let you know when I get some UHD's.

    Yep, I figured this would probably be the case. I do have a WH16NS40 (NS40) 1.02 firmware bin direct from someone's drive (uncleaned) so this still has it's calibration data.

    I was hanging onto this for situations just like this. I simply didn't mention it as he said he was unable to do the DOSFLASH method.

    Yea I did some digging earlier today and had found one that czary2mary posted for someone else with the same symptoms. He basically took the dump from a working drive and replaced the encryption key data. The person dosflashed it and was able to recover the drive. THIS is why I extracted all my original firmware from each drive before I started messing around. I even extracted the calibration and encryption data to separate hex files just to have them. ;) I really should write a tool that properly migrates the calibration data along with the encryption data. An upgraded data mover tool, if you will....that downgrade enables the firmware while its at it. When I get a minute I may consider it. I need to get back to an Android program I'm writing first.

    I won't recommend either of those drives. Others may have a different opinion.

    You should buy a LG BH16NS55 that can be converted to ASUS BW-16D1HT or right away the ASUS. The drives you checked are also not my recommendation if you want to work with UHD discs.

    Yup....exactly what coopervid said. If you can find the ASUS I'd get that and downgrade it to 3.02 and call it a day.

    @Marty S. McFly,

    I'm pretty sure (but don't quote me on it!) that the WH16NS40 is the USA equivalent of the BH16NS55. I remember reading somewhere (a while ago, so can't remember where!) that it is the same drive, just a different name for different regions. America calls it the WH16NS40 (SVC: NS50) and Europe / Australia calls it the BH16NS55.

    Anyway,

    The drive is fine just as long as it has SVC NS50 on the drive label. (If the drive is brand new, then one would assume this to be the case..) It would most like come with firmware version 1.03 so would need downgrading to 1.02 or cross-flashing to another firmware for UHD Readability.

    The NS40 is the same as the NS55? Interesting. I did not know that. But given that there's 2 versions of the NS40 out there it you definitely need to make sure the SVC code is NS50.

    Yeah, I read that the 2nd generation WH16NS40, being SVC NS50 shares it's hardware with the NS55.

    I bought my drive last August. Short of removing it, how can I get this information?

    I'm pretty sure the 2nd gen (SVC NS50) WH16NS40 came out late 2015 (around October?), so if your's was new in August 2018, I'd say it is a SVC NS50 2nd gen drive. Generally the only way to check is to remove the drive from PC and check the label.

    Or check here:

    Burned a DVD successfully and played back in my Blu-ray player. :dance:No BD's to test yet.
