Since you now have nothing to lose you could remove it from the case and put it in another USB enclosure. Inside the case is a 3.5 inch SATA drive, and USB enclosures for these are plentiful and cheap.
Or you could just get another USB-to-SATA adapter and fit that inside the WD case. The second of the two articles below will make this clear I hope.

Opening A WD Elements 1tb desktop Hard Drive
"If you use an exacto knife or something similar you can slide in on the bottom around the seem. I just went all the way around with that, and then did it again but gently pried outward a bit, and it popped off. "

Western Digital Elements External Hard Drive Disassembly
"You can find a seam on the bottom of the drive, all around the edge. If you slip a miniature flat-head screwdriver, you can easily pry the enclosure apart"
"After pulling the 2TB hard drive out of the Western Digital case, I was able to use it with an USB adapter and within a Seagate USB case. So the internal hard drive is really just a normal hard drive."
