Ok. Would you recommend stopping the current session of ddrescue and
starting again with a more frozen drive?

GNU ddrescue 1.17
Press Ctrl-C to interrupt
rescued:   581315 MB,  errsize:    156 GB,  current rate:        0 B/s
   ipos:   738085 MB,   errors:     585,    average rate:    6571 kB/s
   opos:   738085 MB,    time since last successful read:      19 s
Copying non-tried blocks...

The failing drive is 1 TB and has about 600 GB of data.
