Each disk breaks down into partitions: /dev/sda1, /dev/sda2, etc.
Unplug your new disk, and
>cat /proc/partitionsThis will tell you which device is your existing disk: it's the largest one.
Now plug the new disk in and
>cat /proc/partitionsYour new disk is the one that just showed up and wasn't there before.
Then just
>ddrescue <old disk> <new disk>e.g.
>ddrescue /dev/sdg /dev/sdzand watch the progress meter. It'll be fast when it can read, and slow when it can't, but it'll copy every readable sector without giving up.
Make damn sure you have the disks the right way round.
