No space left on device / No Inodes free OR used / Double mounting

For about a day now I can only create/cp/mv (through terminal or various GUI programs) files on my FAT16 formatted USB stick, of about a few bytes. Doing so with larger files reports cannot create regular file 'XXX': No space left on device I have a NTFS drive, and a USB stick with 2 FAT16 formatted partitions on it, attached to the computer. - /dev/sda1 is the NTFS - /dev/sdb1 is one of the FAT 16 formatted partitions - /dev/sdc1 is the other the FAT 16 formatted partitions (Prior and after unplugging the USB stick while PC was pm-suspend'd, to clear space on the full drive - Seems this may have caused part/all of this issue in hindsight) - /dev/sdb1 is the other the FAT 16 formatted partitions (After unplugging the USB stick while PC was pm-suspend'd df reported: Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdc1 1999360 1999360 0 100% /media/sdc1 /dev/sdd1 1999360 822400 1176960 42% /media/sdd1 df -i reported: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sdc1 0 0 0 - /media/sdc1 /dev/sdd1 0 0 0 - /media/sdd1 _Sub question: Any idea why there are no inodes reported??_ df -i /dev/sda1 reported: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda1 5539908 171718 5368190 4% /media/sda1 umount'ng /dev/sdc1 didn't change the counts. I have verified through Windows that space available more-or-less marries with the 42% listed for the latest mounted device (/dev/sdd1). Any ideas on what is going on? **Edit 1:** The output of du -k --max-depth=1 /media/sdc1 is: 1856 /media/sdc1/dir1 32 /media/sdc1/dir2 1440 /media/sdc1/dir3 18144 /media/sdc1/dir4 8512 /media/sdc1/dir5 54304 /media/sdc1/dir6 3200 /media/sdc1/dir7 27200 /media/sdc1/dir8 41088 /media/sdc1/dir9 11520 /media/sdc1/dir10 128 /media/sdc1/dir11 128 /media/sdc1/dir12 1216 /media/sdc1/dir13 2464 /media/sdc1/dir14 12032 /media/sdc1/dir15 5824 /media/sdc1/dir16 29600 /media/sdc1/dir17 20928 /media/sdc1/dir18 5856 /media/sdc1/dir19 4352 /media/sdc1/dir20 659200 /media/sdc1/dir21 121600 /media/sdc1/dir22 22688 /media/sdc1/dir23 128 /media/sdc1/dir24 2144 /media/sdc1/dir25 6912 /media/sdc1/dir26 19968 /media/sdc1/dir27 9632 /media/sdc1/dir28 960 /media/sdc1/dir29 1088 /media/sdc1/dir30 2624 /media/sdc1/dir31 480 /media/sdc1/dir32 1142944 /media/sdc1
