    I just did some digging for a solution and I don't know that I have one. Does the drive led light flash twice when you put a disc in the drive by chance?

    No it doesn't.

    That's probably a good sign then. So HOPEFULLY it's just a matter of getting the right firmware back on the drive. The 2 led light flash indicates that the calibration data is corrupt or missing which would be a good reason why the drive wouldn't read any media. Since yours isn't doing that, the calibration data should still be in tact...especially since you used the patched windows flasher to flash it which doesn't overwrite calibration data or the digital signature. You can TRY flashing the attached firmware bin with the patched flasher. I made ZERO promises here that it'll work. I don't really know what else to try though.

    That's unfortunate. Hopefully someone with more knowledge than me chimes in with an idea. SIGH

    Did you make a backup of the original firmware?

    Can you please try this. Hopefully it will do the trick.

    Use the modifed ASUS flasher with the firmware attached in this post. It is LG WH16NS40 (NS40) 1.01 that is downgrade enabled.

    OK. The only chance of getting that drive to work again is to use the old DOSFLASH method. You will need to be able to put your computer into IDE mode in BIOS and connect drive to SATA port 0 or 1 on motherboard.

    Use DOSFLASH to dump a copy of your firmware first.
    Then use the EEPROM data mover to copy your drive calibration data to the clean 1.01 firmware I gave you previously to generate a new 1.01 specific to your drive.
    Use DOSFLASH to erase drive.
    Use DOSFLASH to write newly generated 1.01 to your drive.

    I know, but if has has any chance of getting that drive working again, it is to use the old DOSFLASH method. Just hoping that his calibration data is not corrupted.

    No IDE ode in Bios only have AHCI AND Raid options. I am not that good at stuff like this and with the price of drives now I fugue I could just get a new one if this didn't work. Thanks for the help though. :)
