You win some, you lose some.

After a drop, my hard drive was making an intermittent beeping noise and not being recognized by my computer.

I decided to take it apart and found that the actuator arm was stuck on top of the platter when it should be safely docked at the orange landing tray.

I carefully rotated the platter while pulling on the actuator arm with tweezers and unstuck it, bringing it back to the landing tray.

After reassembly, I tested it out again but this time, it made a loud beep, some concerning mechanical noises, then... nothing.

I took it apart yet again and inspected the read/write heads. Well, the picture speaks for itself. They were a mangled mess.

Lesson learned: inspect the read/write heads first before attempting any kind of recovery. Fortunately, this didn't have any important info on it (hence not being backed up!). However, I'd find someone who is better at data recovery than I am to help if I couldn't afford to lose the data. You only get one shot with data recovery!
