The invention relates to an apparatus that is interposed between a storage device and a computing system. The can transform single hard disk drive (HDD) into multi virtual hard disk drive (at least two virtual HDD). The host computing system treat each virtual HDD is individual HDD. The controller which include storage interface signal processor to handle the communication between the host computing system storage interface and the storage device interface; microprocessor to handle program task request; RAM is buffer for programming; EEPROM (ROM) is a firmware (program code) for the task. Using above technology, the controller becomes a solution controller for data security and protection. The controller will prevent any data changes on a read only storage zone. Any changed data will be saved and relocated to a sketch storage zone. The controller will determine and provide the latest updated data to user. The controller's RAM Disk Mode operation will clear all changes if system reboot or power down. The controller's Live Disk Mode operation will not clear any changes when system reboots or shuts down. If needed, the controller can perform synchronization and permanently save changed data into the read only storage zone. If the system or data being corrupted, system can start a new session from read only storage zone with the last synchronization data.
