I can confirm that when you do “Storage restore” command and format the drive, The drive gets wiped and new firmware is downloaded from WD servers but the software directory which was seen to be populated in the public folder does not get repopulated after the storage restore command. – This is a BUG which I had already reported in this post
See the second post in this list of Storage Router issues
