problema with shares

[erfico]

Hello
my f4-220 bought in december 2017 worked fine till a couple of weeks ago. Then one of the drives suddenly failed (i used it just some day before). All other drives were fine and shares worked. Today i noticed that a share was empty.. rebooted the nas. but after the reboot another drive was missing.. even if the green led is lit. Even worse... the shares of one drive are gone.. it says the storage space is used but i can't see the shares..
if i look at the permission tab.. the shares are not listed either..
how can i get back my 8+3+3 tb data?
Thx
