Thanks for that advice. It seemed to have made a difference .... the
rescued data has changed from 0B to more than a 100kB. But there is more
than 6GB of data that matters. Below is the ddrescue status:
Starting positions: infile = 0 B, outfile = 0 B
Copy block size: 128 hard blocks
Hard block size: 512 bytes
Direct: no Sparse: no Split: yes Truncate: no
Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 0 B, errsize: 7880 kB, errors: 1
rescued: 142336 B, errsize: 8275 kB, current rate: 4096 B/s
ipos: 8417 kB, errors: 1, average rate: 1530 B/s
opos: 8417 kB
I kept the disk between the two window panes for about 15min and as the
temperature outside is around 2C, it seemed to have helped.
