I have a Dell server that has an External USB hard drive attached that it's used for backups.
The server is located on a manufacture that use a machine that create high Radio Frequency daily. The server is maybe 30 yards from the source of the RF but the entire building will fill the RF. Most common problems for the server is that the USB mouse and Keyboard stop working daily and the admin has to unplug and plug them back but the worst is that once and up to 3 times a week the Usb Hard Drive disappear and unplug it and plug it back multiple times to even different USB ports does not help until the server is reboot it.
So I believe that the RF are responsible since Other PC on the building has similar symptoms with the USB mouse and Keyboard.
I reboot the server last night and it was Ok all night then the problem come back around 10 AM. We are in the process of looking to see if when it happen the machine that produce the RF has been use or not. Question I have is first do you agree that this can be cause by Radio Frequencies and if yes how can we protect the server from this>
I was thinking of electric arc welding for metal which produces a bit of RF on a broad spectrum as an unwanted by-product but those welders use RF to heat metal doped plastics a bit like a microwave oven
