I had to get a new laptop, and it came with a Toshiba MQ01ABD100 drive.
To disable the Advanced Power Management and to stop the head unload/clicking I've always used:
hdparm -B 255 /dev/sda
But on this machine/drive, it doesn't seem to work; or at least it only works for a short while, and then it starts unloading again.
More importantly, the next time I try to disable it,it says its disabled, but the drive carries on clicking, and the Load_Cycle_Count still keeps going up.
Suggestions anyone?

Is this "short while" in the middle of an active session, or have you suspended/hibernated/rebooted/powered-down, in the meantime?
You may need to look into your power-management settings, and make sure that any wake-up/thaw events reprogram the setting. I had to do that with mine.

Try a different value, such as 254, instead.

No, I've been through all those issues. The system is live, and hasn't even timed-out an turned off the screen.

I've looked into those, and haven't found anything related.

That was the second thing I tried, all to no avail. Its as if the drive ignores whatever hdparm does.
I also just tried (with no success)
hdparm -S 0 /dev/sda

Is there a laptop mode set somewhere? That'd be a conflicting configuration.

I haven't found one yet... that's why I am asking for help.

If you're on Gnome: did you try "gnome-disks" utility? - or another utility if you don't have Gnome? - I found that settings in Gnome are not necessarily reflected in the ones below /etc. And maybe that's true even vice-versa ...
And funny enough: I just found I don't seem to even have a hdparm.conf. But the settings via "gnome-disks" tell me my (built-in) head-clicker disk has APM set to 255 ....
And 'hdparm -i /dev/sda' fully rightly tells me the disk has (amongst other things): " AdvancedPM=yes: disabled (255)"

Although I'm not a Gnome fan, I do have gnome-disks, and again, no matter what I command it to do, my LoadCycleCount still keeps going up.

I'm beginning to think that my drive just doesn't support a 'disable' value for APM. So far my only workaround has been a shell loop that touches a file I don't care about.

I wonder if Western Digital infected the drive model with its infamous "idle3 timer" when it took over the Toshiba product line. There's an "idle3-tools" package that can stop that timer on WD drives. Not sure what the risk might be in using that tool on your Toshiba drive.

It sounds like it does work, but something else is changing the settings on you later on.
I don't think you've said how long your change works for.
I don't recall you saying what desktop you use. It may help people narrow down what might be periodically undoing your setting.

Well, I'm not too sure. Right now it feels intermittent and unrepeatable, at least with a value of 255 and/or 254. And I've tried using a 60 second interval 'touch' with those values. Some times the touch prevents the unload/load,and sometimes it doesn't. Again, I need to attempt a scientific analysis.
Today I've been trying 253 with the 60 second 'touch', and that HAS worked for 24 hours, so I declare that my official workaround (pending better test results).

I use KDE, but there may be a few Gnome utilities/apps also installed. (And this is Fedora 26)
