I tried to run fdisk /dev/sdb which obivously failed but it tried to access sectors 0, 1, 2, 3 which resulted in kernel log messages reporting invalid sectors. I tried to connect the disk with Windows and it was connected immediatelly, the partition is visible, I can read files, create files... No signs of problems visible... I don't know if it tells anything, but Windows reports the disk as USB 2.0 SATA bridge even when connected to USB-3 ports. > >Do you have a USB-2 port on the computer you can plug the disk into, >instead of USB-3? > I tried it, but it is only one and separated on the other side of laptop so I could connect only one connector and the result is the same.
