This works great. I have used it many times over the years. The only problem you will run into is condensation.

You need to keep the drive cold but also limit air flow if you are in a high humidity climate

Ziplocks and those plastic clips you can get to keep chips fresh work great. The cables can get out of the ziplock and still be almost air tight. (Get as much air out of the bag as possible before you spin it up.) ...And set it on a block of blue ice
