HDD partial write protect by DIP switch

The purpose of this invention is to protect data in HDD (Hard Disc Drive) from unexpected write operations by malware or miss-operations. By using combination of a DIP switch and EEPROM, a partial hardware based write protection will be performed.

Description

The main idea of this invention is to (1) add a write-protect control switch (DIP switch) to HDD, and (2) protect MBR/BootSector/OS Programs from unexpected write operations, mainly caused by attacks of Malware, Spyware and Ransomware.

When installing or updating OS, it will change the mode from write-protected to write-enable by DIP switch.

When using in normal operations, it will change the mode from write-enable to write-protected by DIP switch, and prevent from destroying MBR/BootSector/OS Programs.

For easy access by users, DIP switch is preferably placed on the edge or on the corner of HDD (the opposite side of signal pins). This position enables switching operations without detaching fixing cover.

About DIP switch

DIP switch must be located in the opposite side of signal pins, because HDD is normally attached to the bottom side of a laptop PC with a fixing cover.

DIP switch may be located in the corner that is a dead space for HDD.

A small rectangle window in the fixed cover enables switching operations (changing position) without detaching HDD.
