I will try. Thanks all for help.

Sorry, when i put MicroSD on Rasp3, i have same RasPBX, not changed!

I always used Win32 Disk Imager also, and if i put my MicroSD, start Win32 Disk Imager and select an Image OS, i receive an message like: OK all files is writed. But wen i put my MicroSD on Rasp 3 noting change...i have old RasPBX.

Yes Bill, i checked. I use an Samsung microSD Adapter, and checked. I tried in other OEM adapter, no lucky.

Hi, i try SDFormatter and Windows (native) to format my SD Card. No success.

Unfortunately I quit. I'll leave this SD aside and start testing on another SD. I've tried absolutely everything, Windows and Linux computer, GPart, Rufus, SDFormatter, Windows formatting, etc. Even Android phone has already tried, without success. It is simply impossible to format SD so I am giving up.

Hi gdesilva, but when i try reformat i receive an write protection error. With Raspbian distribution i can reformat a lot of times, but with RasPBX i can´t.
