In the WIKI I have been checking spelling and grammar. In the article SD_File_Systems in the Wiki is this line:

file and disk management commands, including SD_Delete_File, SD_Free_Space, SD_Disk_Size, SD_Dir and SD_Psuedo_Format.

The word "pseudo" is misspelled. I wasn't game to fix it on the Wiki as this may be how you spelled it in the command.

Should it be SD_Pseudo_Format or as you have it.
Cheers
John
