I have a USB to SATA bridge which claims to be a ASM1153. It works fine with all the other drives I tried, but not with a Crucial MX100 512GB SSD. I can read approximately the first 1.7GB of the disk with dd and then it stops, always at the same point. Very rarely, when I plug it in, it does not work at all and reports bizarre disk geometry like 0 bytes, or 250GB. I have reproduced the problem with several different computers on both USB 2 and USB 3 ports, with kernels from 4.2 through to 4.7-rc5 (the latest kernel currently available). The exact device is this one: https://shop.pimoroni.com/products/sata-hard-drive-to-usb-adapter Logs follow. Let me know if I can provide anything else. When I plug it in I usually see this: [ 32.407739] scsi 9:0:0:0: Direct-Access ASMT 2115 0 PQ: 0 ANSI: 6 [ 32.408085] sd 9:0:0:0: Attached scsi generic sg4 type 0 [ 39.142436] sd 9:0:0:0: [sdd] 1000215216 512-byte logical blocks: (512 GB/477 GiB) [ 39.142440] sd 9:0:0:0: [sdd] 4096-byte physical blocks [ 39.143419] sd 9:0:0:0: [sdd] Write Protect is off [ 39.143423] sd 9:0:0:0: [sdd] Mode Sense: 43 00 00 00 [ 39.144419] sd 9:0:0:0: [sdd] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 39.148165] sdd: sdd1 sdd2 < sdd5 > [ 39.151671] sd 9:0:0:0: [sdd] Attached SCSI disk But when I try to mount the disk: [ 45.323012] sd 9:0:0:0: [sdd] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 45.323017] sd 9:0:0:0: [sdd] tag#0 Sense Key : Medium Error [current] [ 45.323019] sd 9:0:0:0: [sdd] tag#0 Add.
