I have samsung disk after a while the device is found on /dev/sdb but not the partitions. The smartools is not able to make a test of the unit and the dmesg traces show the follow information about is not able to access sector 0. For me the problem is clear the disk is broken in some hardware part and the PCB board is not able to communicate with the disk. I would like have some other point of view about the problem, keeping in mind is a hardware problem.
