Do I need to uncheck 'Put hard drives to sleep...' if I'm copying files to ext. HDD?

I'm in the need to get outside of my home for a couple of hours. I let my Mac transfers files from SDHC to ext. HDD, so that when I come back home, it will finish its job. My question is, do I need to uncheck the Put hard drives to sleep when possible ? Because my computer is just like a bridge that lets files from SDHC transfer to ext. HDD, am I correct? So do I need to uncheck it to make the job finished without interruption?

Thanks for every reply.
