ReadyNas Duo losing access to shares

Thanks for your response Stephen.

I did clear all the logs. 

No, I don't have SSH enabled and I am not using ReadyDLNA. But I went searching for the SSH option, which I could not find. But I did find the FTP option and was able to start the FTP service. Now I am in the process of downloading all my data to an external drive and that seems to be working for now.

Where can I find the SSH option and can I use that to SSH to the NAS server or would that only give me access to the shares?

Unfortunately, I am running the NAS in Raid 0 (or is that 1) configuration where the one drive is a mirror of the other. I wanted the redundancy. Was that a bad choice? What would you recommend?

Presuming that I have all the data that I care about on my external drive, how do I go about fixing my system? Will a factory reset do it, or is it more complicated than that?

Again, thanks for your help. Much appreciated!!
