Apologies if I'm posting to the wrong place; this is where I was pointed to the last time I had USB storage questions. I have a Maxtor (Seagate) "D3 Station" USB 3.0 SATA disk (0bc2:6125). While it appears to work completely fine, every now and then the following are logged in dmesg: [Oct20 01:00] sd 3:0:0:0: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=0x08 [ +0.000004] sd 3:0:0:0: [sdb] tag#0 Sense Key : 0x4 [current] [descriptor] [ +0.000003] sd 3:0:0:0: [sdb] tag#0 ASC=0x0 ASCQ=0x0 [ +0.000003] sd 3:0:0:0: [sdb] tag#0 CDB: opcode=0x85 85 06 20 00 00 00 00 00 00 00 00 00 00 00 e5 00 [ +0.137088] sd 3:0:0:0: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=0x08 [ +0.000003] sd 3:0:0:0: [sdb] tag#0 Sense Key : 0x4 [current] [descriptor] [ +0.000002] sd 3:0:0:0: [sdb] tag#0 ASC=0x0 ASCQ=0x0 [ +0.000002] sd 3:0:0:0: [sdb] tag#0 CDB: opcode=0xa1 a1 06 20 da 00 00 4f c2 00 b0 00 00 When using smartctl (--health --device=sat), a similar message is also logged: [Oct20 01:09] sd 3:0:0:0: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=0x08 [ +0.000004] sd 3:0:0:0: [sdb] tag#0 Sense Key : 0x4 [current] [descriptor] [ +0.000001] sd 3:0:0:0: [sdb] tag#0 ASC=0x0 ASCQ=0x0 [ +0.000003] sd 3:0:0:0: [sdb] tag#0 CDB: opcode=0x85 85 06 2c 00 da 00 00 00 00 00 4f 00 c2 00 b0 00 Are those the sign of a hardware problem or a kernel bug?
