I can't get that performing correctly. I have a strong suspicion 
I'm even more confused about mounting than the group suspects :<

Can this be run as a user, or are root permissions required.

May I have a little hand-holding please?
My defective drive is /dev/sdc .
Partition /dev/sdb6 {formatted ext4} is much larger than the 
defective drive.
/dev/sdb is a 1 TB rotating platter drive connected via USB.
How do I mount it and run ddrescue?
I'm tired and likely going in circles. Need to get groceries, 
will be back soon.

Thank you for patience.
