ts5400 ftp sharefolder deleted after poweron

[mauri300856]

Hi.
I defibed a shared folder that can be accessed using ftp.
For many months i downloaded my files into this share and all was fine.
Four days ago i powered off this appliance from the main menu (using firefox) and then i moved it to another location of my firm.
Afterwards i powered on the ts5400 but i couldn' find my file: the share was empty.
In the system log i found some interesting informations:
Aug 12 11:46:56 TS5400R5F0 nasapi - share - _apply_settings - INFO- start

Can you help me?
