Yesterday I found out that my extra disk shut down. I don't know what steps to follow from now on. I'm searching online about the error as I found in the logs, and I don't know what steps to follow.

I don't know where to proceed from here. The error seems hardware, but I'm not totally sure. After that, what should I try to do to recover as much as possible? I'm reading about ddrescue now. I don't have space in the other partitions to hold all the data in the failed disk, but I'm only interested in recovering some parts of it as safely as possible. Should I just buy a new disk, try to replicate the original one there, and find out which files are damaged? Or should I create an image as a file stored somewhere else?
1. Buy a large disk that you can use for backups. I use 3 TB Seagate ST3000DM001 because they have the best gigabyte/dollar ratio that I am aware of.
2. Try to mount the file system and backup your files. If you can't get the filesystem mounted, copy the raw disk image to a file using 'dd'. You might have to get the image in pieces using the 'skip' and 'seek' options.
3. Download the disk drive manufacturer's diagnostic toolset and run it. For example:
