If 'smartctl -n standby' is used on Linux, smartctl properly detects the
standby mode and exits, but the drive spins up then.

If 'hdparm -C' is used instead, the drive does not spin up.

Ubuntu bug report:

Reproducible: Always

Steps to Reproduce:
1. have smartd running
2. hdparm -y /dev/sdb
3. wait until the next smartd check
Actual Results:
drive spun up from standby by smartd

Expected Results:
leave disk in standby

The problem seems to have been fixed by the smartmontools people a couple of
days ago:

This behaviour may wear out a harddrive, may I therefore suggest this to be
fixed in the final version of 11.2.
