I'm trying to recover data from a laptop drive using ddrescue. After first getting slow speeds via an external USB case, I connected it directly via SATA inside the desktop computer. However, according to the ddrescue info page: "If you interrupt the rescue and then reboot, any partially copied partitions should be hidden before allowing them to be touched by any operating system that tries to mount and "fix" the partitions it sees."
So how can I prevent the auto-mounting of the laptop drive in the desktop computer? I have no UUID for use in /etc/fstab and since the drive is already so broken it won't mount, I don't know how to get any from it.
Or does the note from the manual only concern the copy generated by ddrescue (an image file in my case), not the original source drive?
Note: The laptop drive is partitioned.
fdisk -l output:
