FAT label is stored to two locations:

  1. boot sector
  2. root FAT directory

Empty label for 1) needs to be stored as "NO NAME " and for 2) either not stored or as "\xE5" (deleted flag).

fatlabel does not handle this correctly and stores empty label as " " which is incorrect.

pali added a commit to pali/dosfstools that referenced this issue Jul 5, 2017

fatlabel: In root FAT directory store empty label as deleted
"NO NAME    " entry in FAT directory is not empty label. Erasing label from
root FAT directory can be done by marking entry as deleted (with 0xE5 char
prefix).

Fixes dosfstools#53

Problems with FAT labels should be now fixed in git master branch.
