Sounds like four possible malfunctions, not hearing what size hammer the rodent was wielding makes it slightly difficult to diagnose. Neither are what you want to read, but sometimes reality is that way.
1. "Thunka" = the bearings are going - gone, no spinnie of the platter, no recovery of the data.
2. "Whacka" = the platter spindel spun out of alignment, "Possibility" of a low speed recovery with both hard and soft recovery devices. *ISSUE* low speed recovery, which you cannot control through *user* level software.
3. "Thuwack -Clink-Klink" = one of the platters disintegrated.
4. "Katunk" = the arm made contact with the platter, arm spun up and away. Physical recovery possible.
If the data is valuable, I would not attempt self recovery. $300 used to be the norm.
If the data is worth less than the recovery fee, attempt the user level devices.
*DO NOT* : place power and cable to the drive, you may only get one shot.
