K
Katherine MooreJul 29, 2025
To replace a failed drive, log on to QTS, navigate to Main Menu > Storage & Snapshots > Storage > Disks/VJBOD, and find the failed drive. Prepare a new hard drive with equal or greater capacity. Remove the failed drive from the device, wait about 20 seconds (or until you hear two beeps), then remove the drive from its tray. Insert the new drive into the tray, install it, and check that the status indicates 'Rebuilding'.
