sd card not mounted after formatting So, I tried to do a clean wipe of my Galaxy SII I1900 variant and flash in Paranoid Android's latest build, and everything was successful, but I realised the clean wipe wasn't that "clean". It did not wipe out anything from my internal data, so my app data and photos etc were not wiped. I tried to wipe it again but it doesn't work somehow. 

For some reason my brain thought formatting the sd card means formatting the internal memory (lack of sleep), and after formatting it, neither my phone nor my computer could detect the sd card anymore. I formatted it using the CWM I think (I held power button and chose reboot->recovery), there was no option to format it in any format, it just formatted right after I chose the option. I am not sure if I plugged it out safely but there wasn't any notifications about it being plugged into the computer.

I don't have a sd card reader and I don't think I have any spare sd cards lying around.. Any help for this poor soul here? :/
Summing up the solution from above comments:

While it's not clear what happened with the card, the solution was quite trivial:


take the card out of the Android device, and put it into a card reader
attach the card reader to a computer
format the card using FAT32 (a file-system both sides can handle easily)
"safely remove" ("eject") the card from the computer, take it out of the card reader, and put it back to the Android device


Now the card was recognized fine \o/
