Hi to all.

Famous eMMC 3.0 reader from HardKernel Rev 0.1 doesn't read a eMMC 16 gb red box fresh bought Rev v0.3.x
I done some tests. Trying to access from Windows, MacOs, Linux. Nothin works.

Any ideas ?

So corrections.
PCB Black, Yes, like same picture :). But Linux "Red box"s.
The odroid works fine with it.

The small micro-sd to emmc adapter will work with all of them. https://www.hardkernel.com/main/product ... 5415955758

If you have a supporting phone you could try to stick it into the microsd port on your phone to see if it recognizes the emmc (vfat partition).
Most problems are because it's too thin

Could you take a picture of the pins the eMMC connect on the reader and the pins of the eMMC itself?

I’m having this problem too. When I bought the eMMC to microSD adapter a year and a half ago, it worked great. Haven’t touched it since until this week. Now it doesn’t mount either the same original eMMC nor the new one I just got. I’ve tried it in the USB-microSD adapter I have, and also using the Transcend microSD-SDCard adapaters I have. Seems very strange.
