In this article I cover the replacement of a failing Hard Drive on the QNAP TS-453D.
Here is the manual for the QNAP TS-x53D
Challenges
There are a couple challenges with the TS-453D. Firstly, this NAS was migrated from an older NAS so it created a “Legacy” storage volume and therefore can only handle up to 16tbytes. The only solution is to copy off all the data and build a virtual file system (an expandable “Storage Pool”) from scratch.
Secondly, this NAS was built on 3tbyte Western Digital “CMR” NAS drives. WD migrated away from CMR drives in favour of “shingled” “SMR” drives causing a compatibility issue. Most users are not happy as WD did not notify users of this change.
Solution
Going to purchase a 4tbyte WD NAS CMR drive to replace a failing WD drive:

Update
Ordered the new drive from NewEgg and the drive arrived in about 3 days and the install is simple. I just pulled out the failing drive, let the NAS notice that it is missing, and then placed in the new drive. The NAS automatically recognized the new drive and rebuilt the drive array - this took about 10-12 hours. Once built the NAS is healthy again…
