I have a Terastation TS-RXL/R5. It has worked well for a long time but I needed to move it to a different rack. I shut it down properly, unplugged the power and moved it. When I switched it on again I got a beeping tone, the error lamp came on and the display showed gibberish with a red background. In this state, the power button does not turn it off but just stops the beeping. The fans don't start when I press the power button but come on briefly when I plug in the power cable.
I hope all is not lost because I can see that there is LAN activity briefly and the display scrolls in the normal way.
I am not worried about any loss of data - I have it elsewhere.
It sounds to me as though the flash on the motherboard has been damaged. If so, is there a way to restore it?
Bill.
