That’s the most annoying thing about all this: I had set it not to go to sleep when plugged, just for the screen to turn off. In the morning, I couldn’t get the screen to turn back on and had to restart Windows. Hence, I couldn’t view whatever result checkdisk reported.
As I mentioned, this was one bad sector out of several hundred thousand. I had a pictorial representation of where it was located, but no clue as to where it actually was on the drive or what file was stored there; hence, I don’t know what to relocate. All this was because I was running WD Drive Utilities on all my external drives, having had problems with one of them, and DU failed the 2TB drive on two tests within seconds, without explanation. Everything that unsued was driven by the unhelpfulness of the test software, rather than a specific problem with a file on the 2TB drive.
So now I’m googling " how to isolate bad sectors," which apparently checkdisk can’t do. The problem with all of this is that, whatever problem you identify, almost everyone has software they hope to sell you, so it’s hard to know who to trust. Do you have any recommendations for how to identify and isolate a specific bad sector?
