WH14NS40-NS50 vs WH14NS40?

[xunil76]

are these 2 drives the same?

trying to flash my WH14NS40 drives, but the "All You Need Firmware Pack" only has the "DE_LG_WH14NS40-NS50_1.02.bin" firmware file...is this safe to use on the standard WH14NS40?

The difference is the SVC code written on the sticker on top of the drive.

The older NS40 with SVC NS40 would have the older MT1939 drive platform and is incompatible. It will be bricked if flashed. These are manufactured approx pre October 2015 although there does also appear to be some fakes coming from China with new labels on them, just to make things more confusing!

The newer NS40 with SVC NS50 has the more recent MT1959 drive platform and is compatible.

To see if your drive is compatible, the main things to check are:

Manufacture date after October 2015
Drive platform is MT1959
SVC code is NS50

If all 3 are not as above, your drive is not compatible.

ah, ok...i was just looking at the model in software and it didn't show that bit...but yeah, the sticker does say N50, so should be good. thanks!

You need to look at the sticker label on top of the drive. You can also copy and paste the MakeMKV drive info and libredrive info sections so we can confirm that side for you.

OK, yep, all good. Although, I would have thought you'd flash them with the recommended WH16NS60 1.02-MK firmware?? It reads faster and removes the sleep bug.

thanks

so, does upgrading to WH16NS60 work for the WH16NS40 drives as well? i have multiples of those

edit: nevermind, just saw the recommended firmware versions in the Ultimate drive flashing thread

Yeah, so long as the drive is compatoble (MT1959, SVC NS50+, manufactured after Oct 2015).

WH16NS60 1.02-MK is recommended for all 5.25" LG internal drives (WH14NS40, WH16NS40, BH16NS55 etc) and also the ASUS BW-161HT (which is a rebadged LG).
