+For those looking to go the _shucking_ route, keep in mind the following:

+- You void your warranty by removing the disks from their enclosure. WD might be lenient
+  when you RMA them, but know what you're doing.
+- Not all models have white drives and some models are known to have many issues (like the 6TB drives
+  from WD). Check out [/r/DataHoarder](https://www.reddit.com/r/DataHoarder/)
+  for up to date info.
+- Be sure to check the entire disk in its enclosure. You can easily RMA it if you find defects, and
+  you know you're putting something working into your machine.
+- White drives use a newer SATA spec, which re-uses a pin to disable power to the drive. If your
+  system or power supply cannot handle that, the disk will not start-up. This issue can be easily
+  fixed [by using a piece of tape](https://www.instructables.com/id/How-to-Fix-the-33V-Pin-Issue-in-White-Label-Disks-/).
