Installing a drive inside the TerraMaster F2-212.

How to replace a drive inside TerraMaster NAS



A drive won’t last forever. Be it a mechanical hard disk drive (HDD) or solid-state drive (SSD), it will inevitably fail. A NAS enclosure can have more than one drive installed, so what happens when one eventually fails inside a TerraMaster NAS? If you’re using RAID, the TerraMaster OS should be able to quickly add a replacement drive into the array and rebuild the RAID. Here’s how to go about it.

Which NAS drive to buy

To replace an existing drive that’s gone bad, you’ll need a replacement available and ready to go. If you haven’t already bought one, be sure to check out my collection of best NAS drive recommendations. NAS operating systems, including those on prebuilt enclosures and dedicated platforms such as TrueNAS, will require a replacement drive to be the same size or larger.

It is possible to use a traditional desktop-class drive, be it an HDD or SSD, but I’d always recommend against this if you’re using the NAS enclosure in a live environment, storing sensitive data, and the server itself will be online for prolonged periods. NAS drives such as the Seagate IronWolf and Western Digital Red families are designed with NAS in mind.

Having a spare drive or two will ensure you can quickly replace any damaged or dead storage drive without having to wait for delivery. It’s usually best to have one available in protective packaging and stored at room temperature. Should a TerraMaster NAS encounter issues with one of its drives, the spare can then be unboxed and installed.

The process of replacing a drive inside a TerraMaster NAS is incredibly straightforward, especially if you’re using some form of RAID (which you should be!).

  1. Remove the tray with the failed drive.
  2. Extract the failed drive.
  3. Install the replacement drive.
  4. Reinsert the removed drive tray.
  5. Log into your TerraMaster NAS.
  6. Open Control Panel.
  7. Go to Storage Manager > Storage Pool.
  8. Click Edit.
  9. Click Repair the RAID.
  10. Select the replacement drive.
  11. Click OK.

The TerraMaster NAS and its operating system will now rebuild the RAID using the fresh drive. Once this process has been completed, your data should be available without anything missing, though I’d recommend checking the integrity of the storage pool to ensure nothing has disappeared. As always: back up, back up, and backup!
