Could be a power issue however its more likely a driver issue. AMD Chipset drivers are not native to windows. Get a dock and see if it works externally. [URL] [URL]   Advanced format drives REQUIRE F6 mass storage drivers to "see" a drive. Past 2TB these drivers are NOT optional. Drive must be GPT partitioned because MBR is 2TB MAX. [URL]   [URL] This is not a sound byte single click reboot and you are done.   [URL] Beyond 2TB requires F6 driver AND UEFI GPT Partition. For a system to be able to address the maximum capacity of a device that has a storage capacity of more than 2 TB, the following prerequisites apply: The disk must be initialized by using GPT. The Windows version must be one of the following (32-bit or 64-bit, unless otherwise noted, but including all SKU editions): The latest storage drivers from your storage controller manufacturer must be installed. For example, if your system uses an Intel storage controller that is set to "RAID" mode, make sure that you have the latest applicable drivers from the Intel support site. Overall, you should contact your system vendor to determine whether the system supports device sizes of more than 2 TB.  
HI.   I've just bought an AUrora R11 from Dell Outlet which had a 2TB hard drive along with the NVMe boot disk. I was going to replace that with a Western Digital 8TB (new and working) but it is not recognized by either the OS or the Disk Management utility in Windows 10. I booted into the BIOS to see if there were any setting I needed to change but found that the amount of setting changes available was err a little thin! I was expecting more, but then I'm coming form a self built machine where everything is configurable! Any ideas why this drive cannot be seen even at the DM level? 
Aurora R11, does not recognize 8TB drive
