You could :
1. With the assistance of the shop that you've bought the hdd (鋪頭代收).
2. delivery service (someone told us ... $40 will get the job done)
3. go there by yourself (then you will get back a brand new hdd right away)
We better check with the shop regarding option 1 before buying the Toshiba hdd. I did ask for ... if "鋪頭代收" is available
