QNAP TS-432XU(4.3.6)更換故障硬碟

 一台QNAP TS-432XU(4.3.6)有4顆硬碟做RAID5，最後一顆硬碟已出現警告建議更換，雖然還可以用，但這顆硬碟的讀寫速度慢很多，所以影響到一些日常作業。

原本同型號的硬碟停產了，所以就買一個同廠牌同容量，但轉速更快的來換。

雖然知道是熱插拔，但一開始還上網看一下是不是要在管理介面上做什麼操作，後來查到的畫面又跟自己的不同，就決定直接插拔更換了。

插上後系統就自己在重建了，蠻方便的，剩下就讓它跑完重建程序了。

Replacing a Faulty Hard Drive on QNAP TS-432XU(4.3.6)

On a QNAP TS-432XU(4.3.6) device with a RAID 5 configuration using four hard drives, the last drive started showing warning signs and advised replacement. Although it was still functional, its read and write speeds had significantly decreased, affecting daily operations.

Since the original model of the hard drive was no longer available, I purchased a higher-speed drive from the same manufacturer with the same capacity as a replacement.

While I knew that the device supported hot-swapping, I initially checked online to see if there were any specific actions required through the management interface. However, the instructions and screenshots I found were different from what I encountered, so I decided to proceed with a direct replacement.

Once I inserted the new drive, the system automatically initiated the rebuilding process. It was quite convenient, so I allowed it to complete the rebuilding procedure.
