I had problems with the card on my Note 2, so I tried to format, and now this is the error I get- "SD card is blank or has unsupported file system". I have no access to it (no drive/card reader) except through my cellular - and there it doesn't show. – Toms’ Hardware

But the SD card is prone to get corrupted or damaged, and eventually results in data loss.

If an SD card keeps showing “SD card is blank or has unsupported filesystem” error, then it has been damaged already. So your computer or phone can’t read the SD card and says it's blank. Whatever the reasons, your card can be repaired with simple steps, as the data is still there.
