Public bug reported:
The SMART Data & Self-Tests On/Off toggle control can be used to disable
SMART data collection for the disk. It works for the duration of the
session but it is always re-enabled after a reboot.
I don't know whether the problem affects all disk types but it has
certainly been an issue for my Hitachi HDS722020ALA330 for the last few
versions of Linux Mint, at least as far back as Mint 16 and up to the
present. I presume it must exist in standard Ubuntu versions too.
Background, possibly irrelevant, justification information:
The disk in question is relatively noisy and produces heat. It is only
used for occasional backups. I would like it spun down most of the time.
For my disk the APM spin down is prevented from working by the SMART
data collection. This is why I want to disable SMART.
I believe the problem of SMART data collection preventing spin-down is
an issue that only affects certain models of drive. It's something I
looked at over a year ago and my memory is a bit rusty. I do remember
coming to the conclusion that disabling SMART was the only viable work-
around for my system.
