System Corrupt - it is more like something you should expect to happen. It happened to me 4 times out of 6 open-e products. Usually resulting in a new device being sent to me, but one time there was data loss of the entire server.
I have just tried to update from CD and it didn't work, and I can't find the current version of NAS-R3 as a demo CD. So I am rather unhappy at this moment.
