The CRC errors means the disk contains bad sectors. You need to clone the disk to a new empty disk.
You can use gnu ddrescue from a Linux LiveUSB, see https://www.cgsecurity.org/testdisk.pdf for the details.
Once the copy is done, remove the original disks and try to access your data on the clone
Good luck
