I've formatted my microSD 32 GB Sandisk SDHC 3, Class 10 with SDFormatter which I was using on my raspi3 apparently with no issues. But now I can't read it on my pc (Win7) or any other one. I've tried with a SD adapter and with USB adapter with the same results: it plugs and unplugs constantly.

When I put it on my phone (Aquaris BQ M5) I format the card correctly, I keep getting the same issues when connecting the card "directly" to the pc BUT if I keep the card on the phone and connect the phone on MTP I can copy and delete and open files without problems... but I don't know how to give it format since there or use DISkPART or something similar.

How could I properly format my SD to install Raspbian on it?

You don't need to format your mSD for installing Raspbian; instead, you simply "flash" the Raspbian image file: that simply writes the image file to the mSD from start to end. I highly recommend using Etcher which is available for Linux, OS X, and Windows. It can be run without installing, is easy to use, and checks that the image was flashed correctly.

  • I've bought a different mSD today: it seems that I have a faulty reader AND two faulty front USB connectors. So I guess my question lacks the facts to be a proper question as I don't have any certainty of why any of this happened. So I guess I should delete the question. And btw, thanks for etcher.io, I was going thru the SD Format + Win 32 Img process.

    Your question is still valid: how do I format my mSD for Raspbian? And the answer is: you don't need to. I would suggest keeping the question and also your feedback comments; you should even add them as a note to the footer of your qiestion.
