your pc will not be able to recognize your xbox hdd. What exactly are you looking to accomplish? Are you going to get another hdd for your xbox? If that is the case, you can just use xboxhdm to clone the old hdd to the new one. If you just want to have a backup of the stuff you have on the xbox hdd, I believe you can get something from the usual places to help your pc recognize the hdd, but I'm not sure someone else would know.
