Hard disc data protecting system and protecting method thereof

Abstract

The invention provides a hard disk data protecting system and a protecting method thereof. The hard disc data protecting system is applied in a portable electronic device which comprises a power supplying device and a hard disc. The power supplying device supplys working power to the hard disc. The hard disc working power enables the hard disc to run. The system protects the hard disc data. The system comprises a power switch module, a backup power module and a power detecting module. The power switch module is applied for controlling whether the hard disc working power is supplied to the hard disc. The backup power module provides a backup power supply for running the hard disc. The power detecting module judges whether the hard disc working power is normal or not. When the hard disc working power is judged by the power detecting module to be abnormal, then the power detecting module controls the power switch module to cut off the transmission of the hard disc working power and the further controls the backup power module to supply backup power to the hard disc. In this way, the backup power can make the hard disc to continue the processing on the unprocessed hard disc data when the hard disc working power is abnormal. The hard disc data is thus prevented from being damaged and lost.

Description

technical field [0001] The invention relates to a hard disk data protection system and a protection method thereof, in particular to a hard disk data protection system and a protection method for detecting whether the hard disk power supply is stable through a circuit. Background technique [0002] Notebook computers are mainly powered by batteries and transformers. Due to the need to carry and move, the use environment is not limited to indoors, so it is relatively easy to encounter unstable power supply. Unexpected power failure happens when the hard disk is being stored. If the data is fetched, the hard disk reading and writing process will be interrupted suddenly, resulting in data damage or loss, and it is more likely to cause hard disk failure. [0003] Although an uninterruptible power supply system (Uninterruptible Power Supply, UPS) or a mobile power supply unit can provide extra power for a notebook computer when the battery is exhausted, it is not only for the har...

[0002] Notebook computers are mainly powered by batteries and transformers. Due to the need to carry and move, the use environment is not limited to indoors, so it is relatively easy to encounter unstable power supply. Unexpected power failure happens when the hard disk is being stored. If the read and write process of the hard disk is interrupted suddenly, the data will be damaged or lost, and it is more likely to cause the hard disk to fail.

[0003] Although an uninterruptible power supply system (Uninterruptible Power Supply, UPS) or a mobile power supply unit can provide extra power for a notebook computer when the battery is exhausted, it is not only for the hard disk of the notebook computer, especially the power supply between the notebook computer and the hard disk When there is a problem with the relationship, it will still cause the loss of hard disk data or damage to the hard disk
