I wanted to partition my sd card today (with adb) have downloaded everything driver etc, but as soon as I'm at the command sm partition disk: 179: 192 mixed 50 is the following error message

Error: java.lang.IllegalStateException: command '25 volume partition disk: 179: 192 mixed 50 'failed with' 400 25 Command failed '

the number 25 is replaced by another at each attempt

I have a Huawei p8 lite 2017 with android 8.0 and emui 8.0 developer options with usb debugging and oem unlocking enabled

Why do you want to partition your SD card with adb?

So your SD card is in the phone (P8 Lite 2017) and you want to use the PC to partition the SD card in the phone?

Is not there better way to do that? Do you have no SD Card Reader s.PC?

It is a micro sd card I could use the adapter, we can then partition them so that in android the microsdkarte is recognized as an internal memory?
