Applicable Models​

D1 SSD Pro

Troubleshooting steps:

  1. When connected to USB 4 or Thunderbolt 5/4/3 ports, the D1 SSD Pro's indicator is white; when connected to USB 3 ports, the indicator is yellow. A white indicator means the device is operating in high-speed transfer mode.
  2. Please use the original data cable with the TerraMaster logo and connect directly to the computer's Thunderbolt port.
  3. If installing a brand new NVMe SSD, go to the computer's Disk Management, initialize the hard drive as GPT partition format, create a simple volume and complete partition formatting before the drive letter will appear normally on the computer.
  4. If using an older NVMe SSD, it is recommended to wipe the SSD's PCIe gold finger contacts with an eraser, clean them, and then reinstall.
