I recently purchased a 4tb WD40ezrz drive. From what I understand these are formerly green drives running at 5400rpm 32mb cache. Fine for my usage as an internal drive for storing files. In total I have four internal drives and one external drive, the 4tb replaces an old 1tb drive I've been meaning to change for some time now.



Last night my pc crashed, I don't know if this is related but since I've had it up and running again, I have trouble accessing files from this drive. For instance movie files take ages to load and if I select or skip to a different time along the movie, it will take ages or the movie will hang. Transferring files to and from the drive usually cause it to hang, not always. I was able to transfer one 1.2gb file without problems.

Event viewer shows a bunch of DISK(source) issues error detected during a paging application or something like that.
I was able to run a benchmark on hdtune but it took a while to get started and the program froze shortly after it ended. Running the WD proprietary program to do a SMART test doesn't even recognize the drive. Actually, it recognizes all my drives, but there are two separate areas, one that shows the drives, and another where you are able to select a drive for testing, both my WD drives no longer show up in that area.

And just now, the drive disappeared and reappeared showing that prompt that shows up when you put in a usb or external drive....


What are the chances this is due to a bad cable or even a poorly connected one rather than an actual disk failure? Also it's odd the WD program no longer recognized both my WD drives and a third external drive, only two toshiba backup drives.

Bad cables, connections and power can also cause those symptoms as well as bad fragmentation. You could also use https://www.hdsentinel.com/download.php to check on disk's health.
 
Thanks.

The drive disappeared shortly after I posted. I was able to tighten the connections but I have no spare cables just yet. The drive showed up again but still freezes up whenever I try to access it. I downloaded the free version of hdsentinel it shows the drive as fine. HDtune hangs as soon as I try anything. I also tried a quick error check on the tools menu for windows but that came up with no problems. Currently running another one with the "scan and attempt recovery for bad sectors" box ticked.

Doesn't seem like it's a simple matter of replacing the cable...
 
So overnight I ran the "scan and attempt recovery for bad sectors" scan, it finished in around six hours or so showing no errors but I still had trouble accessing the drive. Shortly after it disappeared and is no longer detectable.
