Flash Drive

Hidden partitions on hard drives and USB flash drives store files, recovery and utility software. Many personal computer manufacturers use a hidden partition for the recovery software and no longer ship software CDs. Some people use hidden partitions to store files, which contain sensitive, illegal or private data. Since most USB flash drives are marked with the drive size, you can check for differences between this marking and the capacity reported for the drive. Any significant disparity may indicate the presence of a hidden partition.
