So, my phone managed to corrupt my 8GB micro SD to the extend that it can't even connect and see the data again. I am on vacation and have no possibility to use a PC (normally I just format the card with my PC). I do not want to recover any data, I just want to use my SD card again. I have a rooted Huawei Ascend Y300, rooted with towelroot (so no custom ROM, just terminal emulator and everything.) Android does not even recognise the SD card, is there a way to format it?
