I'm not sure what's considered "high powered" but the Samsung = tech specs say this particular model uses 5.7 W on average and 10.0 W = maximum. But it does seem curious that the Raspberry PI OS will boot = this disk without issue, so I don't think it's the drive. I also tried a = Samsung 950 PRO using a different enclosure (QNINE NVME Enclosure, M.2 = PCIe SSD (M Key) to USB 3.0 External Case), but it behaved the same. > . . . >=20 > Then you need to use a powered hub for that device. I should have just referred to independent power. You had written: QUOTE I'm trying to use a SAMSUNG (MZ-V7E500BW) 970 EVO SSD 500GB - M.2 NVMe, = attached via the Geekworm X872 M.2 NVMe 2280/2260/2242/2230 SSD = Expansion Board. END QUOTE = https://geekworm.com/products/raspberry-pi-4-x872-m-2-nvme-2280-2260-2242-= 2230-ssd-expansion-board shows that it has its own power connector and has an image that says "please power x872 via DC Jack of XH2.54 connector if SSD is not recognized or low power". Later text on the page says: QUOTE Specifications: Power Supply =E2=80=A2 5Vdc +/-5% , Powered by Raspberry Pi USB port =E2=80=A2 5Vdc via DC power jack or XH2.5 connector, Extra power = for the SSD END QUOTE So, if I gather right, you need to connect a power supply to the X872 and another to the RPi4B. Another image says "Note: NOT recommended to use SAMSUNG SSD, if use SAMSUNG SSD, please close WiFi".
