Hi, I have a Samsung 850 Pro SSD which is currently in a USB 3.0 / UAS external enclosure. The Samsung SSD uses a 512 byte physical and logical sector size, and when it is accessed via the usb-storage device, this is what I get. In a vain hope that I could get discard working, I built a kernel that included the uas driver, and discovered that when I accessed the drive using the uas driver, it showed up as a 4k physical sector device, and this caused device-mapper to complain that the dm-crypt partition was misaligned. Is this a problem with the hardware, or with the UAS driver? - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
