Unresponsive ultra 2 plus
This morning my U2P was not 'visible'. ping does not work - destination host unreachable. Power button would not shut down the box and no access to Frontview.
I rebooted with 5 second power off then power on again. RAIDar sees the box booting and file system check shows 100%, then the device disappears from RAIDar.
I have done various reboots and at one point, after moving the box to another place, I could connect to Frontview and checked the logs and it had nothing wrong. I started to download the logs then the device disappeared again and I could no longer access it.
It seems like sometimes the device can be pinged, other times it's not reachable. I tried both ethernet ports, different cables, different routers, but in all cases now I cannot map the drive in Windows and I cannot use Frontview to access the box and the box has to be shut down with the 5 second hold.
I ran wireshark when trying to access the box with Frontview and I see lots of TCP SYN packets, followed immediately by RST/ACK from the NAS. Having rebooted for the nth time, ping is responding this time.
Interestingly, if I ssh to the box now, I get the TCP connection, e.g. SYN/SYN-ACK/ACK, but then nothing else from the box...
It sounds like a network hardware issue - we have had some odd problems over the last month which could have been network related. Is there anyway to connect a PC directly to the NAS without using a router?
Anyone seen anything similar?

- I tried both 1 and 2 disks in the drive, no luck, finally Netgear told me to ring support. Did a factory reset with a new drive and same problem, so they're RMAing the chassis and I get a replacement tomorrow - for the sum of A$40.
I'm in the process of pulling the data off the drive in an Ubuntu VM, but it's very slow. I'll put a couple of the WD RED WD30EFRX drives in instead and see about RMAing the Seagate drives anyway. - Even weirder, the new chassis arrived today, works fine with the new WD drive, but if I put the old drive in, it gives the same problem...
Oh well, belt and braces, new chassis, new drives... - Unbelievable...
Two years on and exactly the same looking problem occurs...
No ping, no direct access, no RAIDar
I came back from a few days away and found it unresponsive with both disk LEDs lit. I had to power down with 5 second power button - system came back on and no disk lights lit any more and no access at all.
The warranty ran out last year.
Anyone experienced similar problems and got any process to help diagnose.
Cheers
