initial power connection power jolt to disks
I have a H2, connected are a NVME SSD and two 500GB SATA mechanical disks.
H2 is disconneced from grid power.
When I connect the H2 power supply plug to the wall power socket, so applying power to the power supply,
I hear for maybe one second a mechanical disk trying to spin up and then immediately stop again.
So it sounds like if initial power comes from the outside, power is send to the disks, but then the H2 decides "oh, wait, no, I'm actually off, don't spin up disks" and removes power from the disks again.
Obviously this power jolt with every power connect/disconnect to the disks cannot be good for them over a longer time.
And I prefer to hard disconnect shutdown devices from grid power, so e.g. the H2 does not waste 0.x W for just showing the red LED. Off means disconnected from grid power.
Can someone else reproduce this problem?
Is there maybe a UEFI setting for this? (But I think "don't start up when power is applied" is a good UEFI default, there's an option for that)
This is a rev.A board with the original power supply shipped with rev.A.
UEFI was meanwhile upgraded to version 1.05.

Re: initial power connection power jolt to disks
Dear All;
I've got exactly the same behavior here, if I disconnect the power from the board, and then reconnect the power back on, the disks spool up and then spool down.

Re: initial power connection power jolt to disks
Thank you for confirmation.
I'm beginning to question my own sanity as I seem to be the only one who listens to start/stop sounds of Odroid attached harddisks - and cares that they are properly started and stopped so that they are not hurt unnecessarily. (See also older posts for HC1 viewtopic.php?f=97&t=29069 or C2 viewtopic.php?f=139&t=26280 .... :-/ )

Re: initial power connection power jolt to disks
I've noticed this as well. Is it possible to just set it to go ahead and boot when power is applied? This way no unwanted jolts, then you could just shut it down if you need it plugged in and off. Might be nicer on the drives. Just a thought.

Re: initial power connection power jolt to disks
You can set the state as S0 on BIOS then, H2 boot automatically when you power cord in.
In BIOS,
Chipset ->South Cluster Configuration ->Miscellaneous configuration ->State After G3 [S5 state]
Change the Item State After G3 [S5 state]---->>> State After G3 [S0 state]
The HDD will keep turning on when you power cord in.

Re: initial power connection power jolt to disks
That is a temporary workaround, but an unsatisfying one.
I have an extension power cord with multiple sockets and one master power switch. All my "toys" power supplies are plugged into it.
I turn on the master switch when I want to work with them, I disconnect everything with the master switch when I'm away.
But I don't want to work with all "toys" at the same time.
So I turn on the master switch and of the 3 H2 in my mini cluster I only need one, so I would press the power button only on one of them. The others should stay off and not every H2 jolt their disk everytime I press the master button.
The H2 needs to be fixed here?

Re: initial power connection power jolt to disks
If you have to share a master switch with other devices, the workaround is very limited.
We will check other possible options.

Re: initial power connection power jolt to disks
So... have you been able to reproduce the problem meanwhile?
Have you asked your UEFI vendor for a patch?

Re: initial power connection power jolt to disks
Right. We could reproduce the issue.
The power rail is enabled by default and there is no way to control the SATA power rail before starting the UEFI firmware.
So we can't fix it until we change the hardware design. Sorry about that.

Re: initial power connection power jolt to disks
In the H2+ announcement it says
but NOT for the 5V rail, so the H2+ has still the problem with 2.5" disks?
So readings this... please confirm whether the problem is only fixed on the 12V power rails, so only for 3.5" disks,Finally we also changed the 12V SATA power circuit to improve the suspend-resume power control sequence of 3.5” HDDs.

Re: initial power connection power jolt to disks
Thank you for confirmation.
So my decision in the last days to cancel the planned upgrade to H2+ was the correct one.
Takes time and money, 2.5GB is a nice to have but not essential for me, and it does not fix the harddisks problem.
