Ever since upgrading to W10 my external drive keeps switching on and off every few seconds. I always have to disconnect it unless I need to use the data on it, and then it takes ages to get at the data because it switches out just as I am selecting files.
I cannot figure out why the system is accessing that drive as it only contains backup data. I thought it may have been something to do with indexing, but I have disabled that.
Any ideas as to what to try next?
