ClipSport, File System Error Restart Device or Format to Recovery

Sooo my Sandisk ClipSport was full and instead of using the erase thats in the settings, i formatted it on my Mac and now i get a message saying “File System Error, Restart the Device or Format to Recovery”…

When i plug into my pc, all the OEM firmware that was on it is gone, i cant get the message to go away.

I reformatted it on my Windows PC and still nothing.

I also tried running the Windows Error Check where it checks the drive for file system errors and it said nothing was wrong.

Is there a way for me to flash the original fimware back on it…Its basically blank.

Thank for any help.
