I was formatting my phones micro SD using an adapter in my Asus's SD slot.
After formatting and retrieving the card, the phone said the format wasn't right so I plugged it back in my computer. But the computer no longer listed inserted SD cards. I tried a couple other SD cards from cameras to no avail.
However, on the bottom right corner an icon does appear telling me "Safely Remove Hardware and Eject Media / SD Card".
Tried downloading the driver from Asus but nothing changed. Then tried system restore a couple of times to different restore points but both times the restore couldn't be completed.
