I am unable to format my SDXC card. I have tried all the ways I could come up with, including but not limited to;

• mac disk utility:
  • verify + repair disk
  • Erase partition (zero out, 3 pass, 7 pass)
  • Create new partition table (both with mbr and GUID)

• terminal:
  • sudo rm -rf /Volumes/untitled/*

then I isolated the problem to my music folder. In the folder I've found out there are files with illegal characters as filenames. So I used the mv command and various apps that help rename files but each time I erase them and unmount whenever I mount the files come back.

I am currently at my wits end. I'll be grateful if anyone could help. I can supply with additional information should be needed.
