SMB won't start after Firmware Update

Hey I hope someone has some ideas for me, because this is driving me up the wall!

I performed a firmware update from 1.00.08 to 2.00.01 and everything whent smoothly without any problems, but shortly after this I noticed I could not get SMB/CIFS to start.

Network/Services has SMB/CIFS Sharing and File Access Cache Enabled, along with UPnP.
I can disable and enable these features, and with a reboot there is no change.
(I can get AFP, NFS, FTP and UPnP to start)

The only errors I have in the System Log are:
"The system N5200's [ RAID ] disk usage has reached 90%."
The RAID is sucessfully assembled in the Info logs and I have performed a file system check without errors.

Thecus N5200 Details:
- Loaded with 5x Seagate 750G (ST3750640AS)
- Firmware 2.00.01
- Running Factory Default settings (asside from Admin password & IP addresses)
- No Modules installed

Dear Sir,

Please try to restart the SMB/CIFS again from web configration page:
1. Network->Service->SMB/CIFS->Sharing->Disable->Apply
2. Reboot N5200
3. Network->Service->SMB/CIFS->Sharing->Enable->Apply

If above steps doesn't work, please mail the CONF.BIN from SYSTEM->CONFIG MGMG->Download, and mail to support@thecus.com for us analysis.

Yvon.
