In need of a new AC Adapter. Help please?

After having it for a few months(the hard drive) my cat decided it would be fun to chew on the cord for my AC adapter to it and now i can’t use it anymore. It’s frustrating because i have been putting everything on that hard drive including my side projects.on the back of the adapter it says
Asian power devices
Ac adapter
Model no W8-R12FU
Input 100-240 v 50-60 hz 0.6a max
Output 12 v 1.5 A

The hard drive is a my book. Does anyone know where i can get a new one?
