What should I do if I am unable to format or initialise the hard drive, if the computer is unable to recognise the hard drive, or data copying is interrupted during use of model D4-310/D2-310/D5-300C?

You should reset your device as follows:

  • 1. Install the hard drive on your TerraMaster NAS, then turn it on and connect it to the powered-on computer.

  • 2. Turn the RAID knob to the RAID mode required, then press and hold "RESET" for 5 seconds to allow the new RAID settings to take effect; then, initialise and format the disk in the "Disk Management" options for your computer.

  • 3. If the device continues to have issues after performing these operations, please repeat these operations at least twice.
