In my office, we have a Buffalo LinkStation Duo with two 2TB drives set up as RAID 1. We're a design firm and all files are saved directly to the NAS where they can be accessed and edited by any employee. We have frequent power failures in our building, and three times in the past year or so, the Linkstation (this one and a previous one) has shown an error (E14: The RAID array cannot be mounted) when recovering from a power failure.
Every time this happens, our network guy (from an outside company) takes the whole linkstation away for two or three days, and ONCE we got all of our data back. The other two times, there were huge holes in the data. All files were there, but many showed 0 file size and could not be opened. Obviously this has happened again (last Thursday) and we are supposed to get our stuff back today - hopefully with files intact.
Perhaps I don't understand RAID correctly, but what is going on here that would cause catastrophic failure from a power outage (the LinkStation is plugged into a new Tripp-Lite "Inernet Office UPS") AND make it that difficult to recover data when it is supposedly mirrored on both disks? That was the whole selling point for this system - If a drive fails, swap it out and be up and running. As a semi-literate computer guy who has a home network on a NAS backup (although a single disk without RAID), this just doesn't add up for me. Do we need a new network guy, a different storage/backup solution or is there something I just don't understand? Thanks in advance.
