How to replace a disk with SMART errors

Thanks for the update. Glad it is back to normal. Now you get to go through the RMA process with the old drive. Many of us tend not to use replacement drives in our NAS because they are almost always refurbished drives, and at times are drives not on the compatibility list. They do make good temp storage drives as long as you remember they have already failed once. They can also be useful as emergency drives in case of another drive failure.
