I've got this important 600GB music collection on a failing external HDD, which give me problems for accessing the files, not always but often.
I've started ddrescue to copy the whole drive to a healthy one, and after 12hours running it gives me a remaining time of 37 days.
Any advice? I'm a total beginner with IT stuff.
Extract of the ongoing process:
~$ sudo ddrescue --try-again --force --verbose /dev/sdc1 /dev/sdb1 /home/yourdog/Desktop/logfile
GNU ddrescue 1.23

After two days processing, i look at the content of my output drive, and it says its empty. is it normal? here some pictures:
source drive (failing):

output drive (healthy) you can see its 0,0% full. is it ok?:
