[smartmontools-support] Does smart has to be enabled to trust smartctl -H output?

[Anand G. <ana...@ya...>]

I am getting following output from smartctl -H :

smartctl -H /dev/sda1
smartctl version 5.37 [x86_64-wrs-linux-gnu] Copyright (C) 2002-6 Bruce Allen
Home page is http://smartmontools.sourceforge.net/

SMART Health Status: HARDWARE IMPENDING FAILURE DATA ERROR RATE TOO
HIGH [asc=5d, ascq=12]

The smartctl -a reports that the smart has not been enabled. So can
the output of smartctl -H still be trusted?

Basically having trouble understanding the significance of "Device
supports SMART and is Disabled" in the smartctl -a output. Does it
mean that above conclusion that Hardware is about to fail can not be
trusted?

Thanks,
Anand
