What do you mean "information"? Do you mean regular files, or game save data? If it's not much you want to keep, and you have the space to do so, save your files to another external hard drive, a USB thumb drive, burn them to a cd or dvd, or even save them to a free cloud storage service. If you need a free cloud storage service to use, PM me for a recommendation and to earn yourself extra free space.
If you are talking about a lot of files (many gigs worth), you are better off saving to an external drive or USB thumb drive. Just be sure those drives have enough space for you to save your files to.
