Re: [smartmontools-support]smartctl tries to read error & self-test logs when they aren't supported

[Bruce A. <ba...@gr...>]

Hi Philip,

This is a feature, not a bug.  It turns out that there are a number of
disks on the market whose identify device data indicates that they do not
support SMART LOG functions, although in fact they do.  Hence we try these
commands even if the disk claims not to support them.

One can avoid all system log messages by simply not using the '-a'
argument of smartctl but instead using arguments corresponding only to the
actual supported features, eg:
  smartctl -H /dev/hda
or
  smartctl -H -l error /dev/hda
or whatever is suppported by your disk.

Cheers,
	Bruce
