Public bug reported: I bought a Samsung S2 Portable 3 disk with 1 TB diskspace. It's an USB3 disk, but right now I don't have a USB3 controller. Because it's USB2 compatible it should also work without usind USB3 hardware. The disk itself can be found from the system:

When I was fast enough to bring a FS onto the disk and to bring it up I could use the disk but I also had one time data-loss. This is something I cannot recreate. But the scsi-sense-problems are even coming sometimes when partitions of the disk are mounted. BTW, smartctl cannot find the disk: /dev/sdb: Unknown USB bridge [0x04e8:0x60a6 (0x100)] It might be that the disk simply is a bit new but hey, it's just a disk... Can anyone help with such topics? Maybe it's something with the udev- system, where I only have to disable some automatisms to get a more reliable disk. I don't think the disk is damaged, it runs fine under XP systems without any errors.
