Over three consecutive days, three of our servers have lost their partition tables. Two of the machines were running linux and the third was a windows machine and all of these servers are on an internal network.
It seems unlikely to be the work of a virus or code being executed but I cannot think what else it could be. It's very odd and I cannot work out a connection.
Does any one know what might be causing this? Could this be something to do with power surges?
It seems that the problem does indeed stem from the use of machinery upstairs. After 3 more failures and logging of time, it appears to coincide with the times the machinery was used upstairs. Thanks for your answers.
