Copy folder to RAID5 - unknown size with errors

Trying to use ddrescue to copy a folder to RAID5.
I got "unknown # of bytes " and getting "read errors".
I had to pause the terminal output to make a copy to post here and I do not know if it actually copied anything. I can see some usage in gparted , however , "file manager" shows empty RAID partition for now.

Obviously I missed something in my CLI command.
Any serious help would be appreciated.

Thanks
