To Everyone who have a HDD stuck in raid 0 etc. I have found a fix.
How to:
Download DBAN, burn it into a bootable USB via Rufus.
Then select the hard drive which is stuck in RAID 0 with enter, change the format method to Quick.
Lastly start the format, ( you do not have to sit through the whole process, wait till it is done up to 5%, then shut down your computer via the power button.)
Lastly you can set up your hard drive in the disk management.
Taadaaaaaa...
