I have 2 new drives and purchased the Flash tool single drive flasher for both. Neither are seen and I get " Unable to find yourMakeMKV installation". Any suggestions would help. I was able to flash with the SDFtool but still no joy. I have included screen shots.

Processor Intel(R) Core(TM) i7-6950X CPU @ 3.00GHz 3.00 GHz
Installed RAM 32.0 GB (31.8 GB usable)

Reinstall makemkv to the default directory if it's not

No Change at all.

I've emailed you already about this. I assumed it was sorted as I never heard back from you.

Can you confirm:

1. You are running Windows 10 or 11 (64 bit)
2. You are NOT using a VM
3. You installed MakeMKV in the default directory (which is C:\Program Files (x86)\MakeMKV)

Also, how are your drives connected to your PC? What enclosures or adapters are you using?

Hi,

I am having this same error code, 0xff05c103

Using Win10, makemkv installed on c:, not running a VM. Any help would be appreciated.

According to MakeMKV in your picture, your BU40N is at 1.03 with LibreDrive enabled. Why are you trying to flash it?

Because I don't know what I am doing. It shows up as you see but the drive does not open, the led does not light up. In MakeMKV it won't open when I hit eject. So I was thinking it needs to be flashed, it came this why from who I got it from online.

So what drive is it?

Make?
Model?
Manufacture date?

Then copy/paste the MakeMKV drive info & libredrive info sections.

That error code normally means there's a disc in the drive. Remove it.

It is a lg wh14ns40, product bd-re bu40n, this image has all the info. It won't open for me and MakeMKV says there is no disc.

Who told you to flash bu40n fw to a wh14ns40

Use the recovery option quick back to the correct fw and don't keep the drive powered on when its flashed wrong

I have just been reading the forums and trying to figure it out. The why it is programed is how it came in the mail. I was just trying to flash it not knowing if it was already good or not.

I do not know or understand yet how to make it work. I requested a return from the ebay seller for the drive since it won't open. In theory I am thinking it should just be working like normal at least. I can't afford the preflashed drives yet but really want to back up all of my uhd discs and other older movies with it.

???
it came flashed as a BU40N not a WH14NS40?
not impossible but im thinking you did it not the seller

Maybe it'll be useful to someone.
On Windows 7 Professional SP2 64-bit, SDFtool works like a charm.
I've used it to convert two drives: a Verbatim 43888 (BU40N) and an Asus BW-16D1HT.
Everything works perfectly. Many thanks to the program's creators.
