Dear Ddrescue,

I wanted to use following command on a 2TB disk, because it was taking to much time for pass 5, so tried to use the part of the disk with --cpass=1 first, using hexadecimal numbers to define the bytes to be read. The error message from ddrescue is also given. What am I doing wrong? I couldn't find an example in the official documentation.

sudo ddrescue -f -d -n -N --reopen-on-error --input-position=0x1CD042E000 --size=0x00AC2000 --skip-size=1024,8192 --cpass=1  /dev/sda /dev/sdd ~/Desktop/mapfile
ddrescue: Numerical argument out of limits.

The version I am using:

GNU ddrescue 1.22
