Unfortunately, it's getting to be unheard of for a company to provide free competent technical support (in english) for something as complex as NAS. Especially to trouble shoot and diagnose problem cases. For example, Dell would just refer you to your Windows re-imaging CD.
Your best bet is probably this board, but keep trying with Thecus too. Your reseller, maybe eaegis?, is another place to ask for support. When a storage solution leaves you in a lurch, it is understandable you want responsive support, but it doesn't appear that they're willing to do any hand holding. Sorry.
I'm trying to be hopeful that Thecus is diverting support effort to work the root causes and that they will soon release a firmware and manual update.
