A Red Hard Drive

I have locked my red hard drive in the cupboard of our library the last term during Christmas holidays, then when I return to our campus, when I opened the cupboard, my hard drive had gone.
It is a red one, like a small box and it is 5T, and there are lots of my family photos inside, especially my kids' photos, it is very important to me
So, if someone knows where it is, let me know, I really appreciate it!
Thanks a lot!
