All HP computers reserve a part of the hard drive for the HP Recovery Partition. This portion of your hard drive stores all of the data needed to reset your system to the factory default settings. If you should ever have a fatal system error, you can use the HP Recovery Manager to restore this data and repair your system. Your computer protects these important files by hiding them from view. With a few settings tweaks, however, you can reveal the files on the Recovery Partition. Warnings Writer Bio
