Abstract
A hot plug protection device for HDD's (Hard Disk Drive) is disclosed. The HDD herein refers to an IDE (Integrated Drive Electronics) HDD. The protection device is installed in the interface module of a computer-implemented apparatus. The protection device contains a power control module and an information control module. When the computer-implemented apparatus is working and one need to hot plug an IDE HDD, the power control module controls the instantaneous electrical power during the hot plug procedure. The information control module is further used to control the information transmissions between the IDE HDD and the computer-implemented apparatus. The invention achieves the objective of protecting both the HDD and the computer-implemented apparatus during the hot plug action thereby.
Claims10
A hot plug protection device for HDD's (Hard Disk Drive) implemented in an interface module, which is configured with an installation signal and through which the protection device is connected to a computer-implemented apparatus comprising:
- a power control module connected to the HDD for detecting the connection between the HDD and the interface module and sending a work voltage to the HDD after receiving the installation signal;
- and
- an information control module connected to the computer-implemented apparatus for receiving an enable signal sent out from the computer-implemented apparatus, transmitting the information on the computer-implemented apparatus to the HDD, and transmitting the information on the HDD to the computer-implemented apparatus.
