Ticking could be the click of death. If the data is critical, then don’t do anything with the disk other than to try and extract the data.
For a home-made option:
When I had no other option with a clicking drive I extracted it from its case and mounted it on a usb cable caddy. I cooled it down by putting it in a food bag and then placing an ice block from the freezer above and below it. (This method allows me to keep it cool by cycling the ice blocks).
Before I did this I made sure that I had a spare drive(s) to hold the rescued data, and what ever recovery software I was using cued up and ready. Cool it down, see if it mounts, and if it does, start getting the data off, most important data first. Swap the ices blocks for frozen ones as needed.
