Greetings,
The journey continues...
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
