Hi, my comments below.
Best guess, assuming no issues with the hard drive, is there is a problem somewhere in the steps you are using to unbrick. Generally what I do is download the directions to the Linux PC then copy and paste the various commands from the text file to the Linux terminal window. Adjusting of course for the hard drive location (/sda or /sdb, or /sdc, etc.) if needed

Make sure before starting the unbrick process when using Linux to issue the following command from the Linux terminal: apt-get update && apt-get install mdadm parted
[Jaxwins] - Did not made this step
Make sure, at step 5 of Fox’s directions, to enter the values exactly for each partition and in the correct order after removing any existing partitions. Do not change any of the values.
mklabel gpt
mkpart primary 528M 2576M
mkpart primary 2576M 4624M
mkpart primary 16M 528M
mkpart primary 4828M 100%
mkpart primary 4624M 4724M
mkpart primary 4724M 4824M
mkpart primary 4824M 4826M
mkpart primary 4826M 4828M
set 1 raid on
set 2 raid on

Step 8 can be confusing. If you get an error issuing the mdadm --stop /dev/md*
I usually just ignore it and continue to the next command entry in the directions: mdadm -A /dev/md0 /dev/sdb1 /dev/sdb2
[Jaxwins] - Yes, i got erros at this commands and can’t figure out why
When you run this command: mdadm --create /dev/md0 --level=1 --metadata=0.9 --raid-devices=2 /dev/sdb1 /dev/sdb2
you then need to issue the following command and wait for it to indicate 100%: watch cat /proc/mdstat
. Once it indicates 100% then hit the keys [ctrl] + [c] to close that message and proceed to issuing the remaining commands in the terminal window. It is easy to forget or mess up this step as it is somewhat confusing.
[Jaxwins] - Notting happens in this command, don’t see any increasing percentage
