Unable to access public shares

Hi All, I hope someone can help me. I accessed my mybook lastnight over ssh to transfer 250ish gig of files between shares using

mv /DataVolume/shares/Public/Shared\ Music/* /DataVolume/shares/Music/

This worked fine. However this morning I am unable to access the public share. I can however still access the Music share.

I can still see the share in the UI and its showing approx 1.8tb of data within it. However I cant get to it.

Does anyone know how to fix this?
