Get a tool that can read your SMART information, like Speccy, and check what your Re-allocated sector count is. This will show you a figure that relates to the amount of bad / flagged sectors that your hard drive had to evacuate whilst transferring / writing data.
If you're really paranoid, you can try running a full diagnostic with the Western Digital Data Lifeguard Diagnostic tool, or you can run chkdsk on the volume with:
chkdsk letter: /r
example:
chkdsk c: /r
You should get a prompt asking you if you wish to lock handles, if you answer no, you will be prompted with another question asking if you wish to schedule a chkdsk during the next boot. Press Y and restart your computer. Observe the results routinely to see if you have any bad sectors / indexes / clusters being repaired.
Hope that i was useful.
