Hi there Tim_133,
Sorry that you are facing some issues with your WD drive.
It may be a good idea to back up the data until you sort that out.
What is the file system of the drive? You can check that out if you go to Disk Management.
What are the supported file systems by your TV? (NTFS, FAT32, etc.)
Also, you can run both short and extended DLG tests on the drive:

Let me know how this goes,
