What to do if hot-swapping failed drives in QNAP TL-R400S?
- TThomas ArroyoJul 27, 2025
To hot-swap failed drives, log on to QTS, then go to Main Menu > Storage & Snapshots > Storage > External Storage, and locate the failed drive. Prepare a new hard drive with the same or larger capacity as the failed one. Remove the failed drive from the QNAP JBOD enclosure and wait for 30 seconds or until the enclosure beeps twice. Remove the failed drive from the tray, insert the new drive into the tray, and install the new drive.
