Why cant I create a new folder under my SD card on my Chromebook?

[Rumblee1]

Im on an asus chromebook c201. Why cant I create a new folder under my SD card? I can add one to any other file but I get a message that reads "unable to create new folder". The file or the directory is not usable. The funny thing is that I have all my music stored on this card and it has over 52 gbs left for storage.

The SD card could be corrupt, defective, or counterfeit. Eject the card, remove it, and insert it into your PC. Can the computer create a new directory? If not, backup as much as you can right now, then run chkdsk to look for bad sectors: http://forums.androidcentral.com/am...guide-using-chkdsk-fix-corrupted-sd-card.html.
