Turn off Time Machine in Preferences.
You shouldn't have to reformat if you don't want to loose your back up.
I keep mine running and at the same time I will copy some large project files temporarily. Time Machine doesn't seem to mind.
You shouldn't have to reformat the drive. Go to System Preferences > Time Machine and click the 'On/Off' swith in the bottom left corner to stop Time Machine backing up to that drive. You may also want to assign a different drive for Time Machine to back up to. You can then take your 'Backups' folder and move it anywhere you want for later use.
