Computer data storage unit reinstallation data protection method and system

摘要

A computer data storage unit reinstallation data protection method and system is proposed, which is designed for use with a computer platform for providing a reinstallation data protection function to a data storage unit that is to be installed onto the computer platform, which is characterized by the categorization of the utilization status of the data storage unit into 3 internal status attributes, including “unused status”, “unrecognizable status”, and “recognizable status” for internal use by the computer platform with the user interface still including only 2 external status attributes, i.e., usable status and has-been-used status. This feature can help prevent the data storage unit which contains data that are still wanted from being mistakenly regarded by the user as a brand new one and thus formatted by the user during installation that would cause all the data in the data storage unit to be lost.
