I was aware of those hats but including postage we're going around €25. For less than an half, I have the 3 in 1 remote and the power supply too and I completely control every function of the RPi (not just turning it on and off).
it allows to fully control the RPi with IR remote control, not onlz power on/off, since the IR signal is forwarded to the GPIO pins of the RPi.
Already done since the beginning as written in my first post but this setup is incapable of switching the RPi on because, as explained by chewitt , GPIO isn't active while the RPi isn't powered.
but you can combine it with the OOTB solution for just powering the RPi up and down.
the first one will work for Power ON/OFF. Since it is for the RPi3, there will be a limitation to 2.5A (at least I think so). The RPi will be powered than over the HAT (similar to my solution no longer available) instead of its own USB connector.
Full documentation of this board will show, how to use it with each kind of RPi.
An additional FLIRC would be needed for full control of LE.
it would be more useful, to get links to the products (as I did). Then is possible to know more of these solutions and how they fit.
this board can be used, it's from german store and needs to be built by you:
it allows you to use two IR codes for PowerOn and PowerOff (learned by board). Maximum power is 2.5A.
it looks similar to my one (bought over Internet from Thailand), but the shop is closed already (no longer available).
another possibility is the Argon V2 case, but some people in the forum have problem with this case and LibreElec. There is also one with space for M.2 SATA drive.
if the RPi is always powered, there are many possibilities, e.g. FLIRC on USB.
after creation of the 8TB partition, did you create a file systen, e.g. with mkfs.ext4?
in your commands I see only fsck.ext4 (probably on an uninitialied partition).
sorry, now explanation in English. I was in a german language forum before answering here.
for best performance on a HDD, the partitions should be aligned to some size, e.g. internal buffer of the HDD (most HDD have internal SDRAM cache of about 64-256MB for performance, aka read and/or write cache). Unaligned partitions are working, but should be avoided. So adjust the command to the initial offset of the partition to 2048s (equal to 1MB).
dann wohl besser für die Performance:
parted -s /dev/sdb mkpart primary ext4 2048s 100%das eine 1MB wird man wohl verschmerzen können.
other option is, to use powered HUBs for I/O USB devices (and do not use any power from the RPi). Too much power used on the USB ports will produce more heat on the RPi and there will be less reserve for short power peaks.
this was my solution with a RPi4 and USB3 problems (disconnected SSD/HDD). Look at the specificatio of USB Hubs! Many can't provide full load on all ports at the same time. 4 Ports USB3 is at almost 20W (each 5V and 0.9A). And don't forget a little bit of overprovisioning.
try to us a powered USB hub. If it is a power issue, it should go away than.
An SSD can take quite some power if it is reorganizing internally.
the RPi4 needs some HAT or closure to support IR, since it is not supported by default. See, you wrote in the beginning.
we both use the same HAT (from MSL Digital). I use on the Harmony the device "Microsoft Windows Media Center" for LibreElec. Worked immediatly for me. I only had to learn PowerON/Off on the HAT, nothing more.
Harmony and CEC doest not work very well together. With CEC the TV talks independently from the Harmony to LibreElec and may change states and internal, in which the Harmony believes.
Which IR on the RPi4 do you use with the Harmony?
which temperature do you have on your RPi4. Mine are usually at low fourties (and the fan is not running).
ypu can set different CPU/FAN releations in the configuration file.
- Button and IR works perfectly so I know the scripts did their job, problem is fan stays off.
did you check the temperature of your RPi4. Below 55 degrees, the FAN is not running, 10% bewlow 60 degrees )you will not hear), 55% speed above 60 degrees and on full speed above 65 degress. The configuration is in the file /etc/argonone.conf file.
You can send commands to the ArgonOne controller over I2C, see Argon-ONE-i2c-Codes.
Good to hear, that the IR is working fine. Is On/Off via IR also working?
for the Argon ONE Fan, you can use the scripts from Argon40: argon1.sh. Usually fan will start at 55 degrees CPU temperature.
there are also some GIT projects for the Argon One case...
The script is not directly for libreelec, but it has the missing functionality for IR from the LibreElec installation script of the Argon ONE.

Raspbian is the OS if it is not Ubuntu in the script. Maybe you get some hints from the script or LibreElec is compatible with Raspbian in configuration. I looked a little bit into the script and it adds the GPIO for IR into /boot/config.txt, LIRC is used for IR communication. looks not too bad.
