My current storage set up is three WD external hard drives (16 TB, 12 TB, 8TB). The 12 TB drive is beginning to fill up, so I purchased a new My Book Duo (20 TB) to replace the 12 TB drive. However, I cannot get the new 20 TB drive to work. When I connect it to the power source, the fan turns on for about 1 second, then turns off. Unsurprisingly, the 20 TB drive does not appear in Devices and Drives.
Could be poor power supply. Can you try with a supply from a good drive?
Thank you for your response to my concern. The drive had been connected to a surge protector that was adequately providing power to other drives. Still, I tried connecting via another surge protector connected to a different outlet. In case the problem involved some weird interaction between the drive and a surge protector, I also tried directly connecting to the new outlet. The results were the same in both cases (the drive turned on for about a second and then turned off). I called WD product support. The engineer there said that the drive was defective and advised me to return the drive for replacement. I did so and received a replacement drive that worked.
