It looks like the problem is in libatasmart. It seems to be throwing
the io error in sk_disk_smart_status here:
/* SAT/USB bridges truncate packets, so we only check for 4F,
* not for 2C on those */
if ((d->type == SK_DISK_TYPE_ATA_PASSTHROUGH_12 || cmd[3] ==
htons(0x00C2U)) &&
cmd[4] == htons(0x4F00U))
*good = TRUE;
else if ((d->type == SK_DISK_TYPE_ATA_PASSTHROUGH_12 || cmd[3] ==
htons(0x002CU)) &&
cmd[4] == htons(0xF400U))
*good = FALSE;
else {
errno = EIO;
return -1;
}
(gdb) print d->type
$5 = SK_DISK_TYPE_ATA_PASSTHROUGH_16
(gdb) print /x cmd
$4 = {0x0, 0x0, 0x0, 0xc200, 0x454f, 0x5000}
