I have a 16GB USB 3.0 thumb drive that has worked wonderfully up until two days ago...
When ever I plug it into a USB3.0 slot:
- The light flickers indefinitely; Nautilus shows the Open/Eject popup as usual but when attempting to open in any file manager it hangs and after a while complains /dev/sdx no longer exists (even though lsblk says otherwise)
- Trying to inspect with gparted produces a similar error, cannot find stat for /dev/sdx - it does not exist.
- And a lot of scary dmesg output that I do not understand at all.
I can modify the device using fdisk. I have tried restoring the boot code and I have tried resetting the partition table and trying various different file systems.
Using the drive in a USB 2.0 slot works normally. Other USB 3.0 external drives and flash drives in the USB 3.0 slots work normally.
The device works on USB 3.0 ports in Windows and other Linux computers.
My main reason for posting is to try to learn and understand what is happening. Any advice is appreciated!
