I recently bought a Ugreen USB-3 external NVMe housing and a Samsung 990 Pro 4TB SSD. They worked fine for a few weeks, including yesterday when I used it to back up my LAN server. Today, every attempt to connect it returns a dmesg error: "Read Capacity(10) failed" and of course it can't be connected. I've tried it on three machines, all with the same result. My quandary is: how can I tell whether the Ugreen controller is not querying the SSD, or the SSD is not answering it? Which component do I return as faulty? The full dmesg entry: usb 3-7: new high-speed USB device number 7 using xhci_hcd usb 3-7: New USB device found, idVendor=0bda, idProduct=9210, bcdDevice=20.01 usb 3-7: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 3-7: Product: Ugreen Storage Device usb 3-7: Manufacturer: Ugreen usb 3-7: SerialNumber: 012938058E61 usb-storage 3-7:1.0: USB Mass Storage device detected scsi host2: usb-storage 3-7:1.0 scsi 2:0:0:0: Direct-Access Realtek RTL9210 1.00 PQ: 0 ANSI: 6 sd 2:0:0:0: [sda] Read Capacity(10) failed: Result: hostbyte=DID_OK driverbyte=DRIVER_OK sd 2:0:0:0: [sda] Sense Key : Illegal Request [current] sd 2:0:0:0: [sda] Add.
