I have a 3TB WD Green disk that was bought as part of a WD Elements external HDD. The external HDD was used for a home media server and was in use for approximately 60-120 minutes per day. It's around twelve months old.
Recently, the disk appeared to show signs of failure, that I've only recognised in retrospect - directories would show as being inaccessible, but I put this down to permissions issues with the server, rather than the disk. The permissions issue would resolve itself by restarting the server. Eventually, the HDD wouldn't show at all. However, when I plugged it in to a different computer, it worked fine. I thought this could then be an issue with the server (an ancient laptop) and its USB ports (even though the WD Elements has its own power supply). I tried a USB Y-cable with the HDD's SS-USB cable and once again it worked. However, after a week or so, videos being streamed from the server would fail and the drive stopped being recognised, so it looked like it might not be a power issue.
I've since tried the Elements unit on different computers, as well as removed the HDD from the unit to try in a different external case (with different power supply and USB cable). All it does now is spin up and spin down several times before giving up (using the Elements interface) or just continually spins up and spins down (using an alternative external interface); with the latter, if it's left on for an extended period it can eventually spin up and stay spinning for 20-30 seconds before spinning down. Other than some occasional light clicks at the peak of it spinning up, there is none of the normal clicking that I might expect to hear from it. After a short while, I'll get a dialogue box telling me "The disk you inserted was not readable by this computer", which I assume means
something is recognisable.
I've installed Smartmontools but can't get anything useful from it. I think the device is recognised as /dev/disk2, but when I try to run an interactive session on it, I get the error "Smartctl open device: /dev/disk2 failed:"
I've made a recording of the activity. It's not great quality, but hopefully it can provide an indication of disk activity:
