From what I can see in shitball.log and shitball2.log, it seems that you 
inverted the drives, copying from the Toshiba to the WD:

# Command line: ddrescue -v -d -f -r 2 -c 128 /dev/sdb1 /dev/sdc1 
/home/travis/Desktop/shitball.log

/dev/sdb1 on /media/travis/TOSHIBA EXT
/dev/sdc1 on /media/travis/Elements

For irreplaceable data in a good drive it is much safer to make backups 
using 'cp -an'.

Given that you only copied 1% of the partition, you may use a file recovery 
tool to try to recover the files in the remaining 99%.
