Buffalo ext drive will not open after Firmware flash

Post by Peabody111 » Sat Sep 26, 2026 5:46 pm

I did the Libre Drive flash on my Buffalo external drive yesterday and it said everything was successful but today when I go to use the drive nothing I do will make the drive door open . Not restarting pc not using pin hole to force eject . Any ideas?

Which firmware did you flash ? Is it a 5.25 drive or a slim drive ? Power it off immediately and, preferably, also make sure it's not plugged in. You might have flashed the wrong kind of firmware and in that case, you need to make sure the drive doesn't get any power until we recover it.

Yes I’m pretty sure I flashed the wrong firmware .
It’s a BRXL-16U3
It’s currently unplugged
I went to Buffalo web site but no firmware is available there .

If you are using SDFtool Flasher, plug the drive back in and try doing a RECOVER Drive, selecting the "wrong" firmware that you flashed in the pop-up window (this is VERY important), then click on the lower drop-down menu and select DE_LG_WH16NS60_1.02_MK.bin (the firmware you should flash - this will hopefully "repair" your drive and make it LibreDrive-compatible and UHD-compatible) from MartyMcNuts' All You Need Firmware Pack (see this thread) : viewtopic.php?t=22896

If it fails on Windows, or if you are using a Mac or Linux, let me know and we'll try the command line instead.

Was the recovery flashing process done completely without error message?

Apologies for the late reply, I am really busy these days but I have just received your PM. I agree that you should post the MakeMKV drive information first, it will let us know more about the issue and how to fix it.

Yeah, you've flashed a slim drive firmware to a 5.25" drive. When recovery with the SDF Flashing Tool doesn't work, try the modified ASUS flasher with the WH16NS60 1.02MK. viewtopic.php?f=16&t=18933

SDFtool Flasher's RECOVER option should work fine for this. Just make sure that:

1. When you select RECOVER, in the popup that appears immediately, you select the BU40N 1.03-MK firmware that is currently on the drive.
2. In the normal firmware drop down box you select the WH16NS60 1.02-MK firmware.
Cheers :D

Ok done that but still the door will not open. What now?
Am I reading this right? The drive Info hasnt changed even after the flash to WH16Ns60 firmware?

Check my post above then. Perhaps more luck with the modified ASUS flasher?
