What to do if a drive fails in RAID 1 on my QNAP TS-451DeU?
- PPatricia ReyesAug 8, 2025
If a drive in your QNAP Network Storage Server configured as RAID 1 fails and needs replacement, access QTS, then navigate to 'Main Menu > Storage Manager > Storage > Disks/VJBOD' to find the faulty drive. Get a new hard drive ready. After removing the failed drive, wait about 20 seconds (or until you hear two beeps from the NAS) before inserting and installing the new drive into the tray. Make sure the status shows 'Rebuilding'.
