I am using Ubuntu 20.04 and wanted to use a live USB stick to partition my hard drive. While partitioning something went wrong and my computer crashed. After restart it shows me that 70 percent of the disk is used, which is not correct.
Is there any way to fix the hard drive without formatting the entire thing and losing all of my data?
EDIT:
Output of sudo parted -l
