S4 network problems...
I have an S4 with 4 2TB drives (RAID 5) that consistantly falls off the network during certain file accesses. I can't see the S4 in my router's IP list, can't access the unit using the web interface. While the unit is off the network you see what looks like a lot of activity judging from the LEDs on the front of the unit. When this happens, I have to power the unit down and reconnect it. It works until I do any heavy-duty data accesses, at which point it disappears again. Anybody seen this problem and is there a fix?
First off, what kind of drives are they? Second, I would try hooking up each drive to a computer and verifying that they don't have any bad sectors. If it still does it, I would try doing a factory reset on the unit.
Try disabling the DLNA service (Administration -> File & Print -> Protocol Control), then reboot.
DLNA is used by certain devices to access the NAS, like smart phones or PS3. If you need the service, you can reboot the NAS periodically. Or, turn on the service when you need it, then reboot after you turn it back off. Otherwise, we hope a fix comes soon.

There could be a drive issue, but that should not cause the unit to disconnect from the network. I would also expect the file system to be able to handle and report disk errors without losing network connectivity. These were new Hitachi 2TB drives, of which I was able to move more than 3 TB of data to with no issues. In fact, in the past writing has not been a problem except on occasions where transfer speeds would fall too low. It's reading that's been the primary problem, especially fast-forwarding through video files.
Those type of drives should work fine for the NAS. I would still run a diagnostic on each drive, just to make sure it's good. I've had new drives arrive before that were bad. Like VulgarHandle suggested, I would also disable the DLNA service. That will definitely help with speed.
