What should I look at?

The disks are inside an USB enclosure, connected to a 13.1-32b machine.


To run smartctl on it I have to stop the machine and take the disk to
another machine that has SATA, because:


AmonLanc:~ # smartctl -a /dev/sdb
smartctl 6.2 2013-07-26 r3841 [i686-linux-3.12.62-52-default] (SUSE RPM)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

/dev/sdb: Unknown USB bridge [0x0c0b:0xb136 (0x108)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

AmonLanc:~ #




Looking carefully, messages start on 2016-09-19T14:58:37.943377+02:00, just
after I applied a kernel update and rebooted:


2016-09-19 14:58:36+02:00 - Booting the system now
================================================================================
Linux AmonLanc 3.12.62-52-default #1 SMP Wed Aug 10 18:37:26 UTC 2016
(069dc39) i686 i686 i386 GNU/Linux


I will have to revert that upgrade :-(

When I see semi-unrecognizable SATA errors like that, I blame the
cables, enclosures, etc.

It is rarely the drive itself in my experience.

As tot he kernel update, I be that turns out to be a coincidence.
