Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

When we use smartctl -C -t long /dev/sdX, the ATA SMART command we send has the usual 20s timeout. This is not enough, the drive usually needs several minutes for the test to complete.

On the command line: smartctl -C -t long /dev/sda

The command times out after 20s. Instead, the command should have a 10 + x minutes timeout, to be sure the device can complete the command before the error handler kicks in. We do know the test will last 10 minutes from SMART data information.

However, looking at the code it seems there is no way today to pass the desired timeout with an ATA passthrough command.

smartctl -a (and smartd as well) gives an error when trying to examine some disks because the response to a mode sense command cannot be parsed (see attached file smartctl.log).

However, if the same command is sent with camcontrol, the response is correct (note the leading byte in camcontrol.log, which is not present in smartctl.log).
