Hard disk anti-vibration device and method

Abstract

This invention relates to a HD anti-vibration device and a method used in a mobile electronic device assembled with a HD set on a support surface, in which, the device includes a protection switch inthe base of the mobile device, one of which is contacted with the support surface and the other end is coupled to a sensor connected with a microprocessor via a modulus conversion circuit and the microprocessor is connected to a supply unit. The method includes the following steps: the microprocessor accesses the state of the protection switch by the sensor to detect if the mobile electronic device with the HD is away from the support surface, if not, it ends the work, otherwise, it controls the supply unit to stop supplying to the HD and detects if the device is reset on the support surface,if not, it continues stopping the supply to the HD, if so, it supplies the HS again.

Description

【Technical field】 [0001] The invention relates to a storage device maintenance device and method, in particular to a device and method for protecting a hard disk of a mobile electronic device from vibration damage. 【Background technique】 [0002] In the daily work of using laptops, short-term short-distance moving often occurs, such as moving from a desk to a meeting room. Under normal circumstances, the distance between the head of the drive and the platter of the disk is very small, it is inevitable that there will be shaking and bumps during the moving process, and when the disk is in working condition, the head is easy to touch the disk, thus Damage to the magnetic head, in severe cases, will scratch the disk and destroy the recorded data in the magnetic medium. This phenomenon is called "head collision". Once this happens, it will lead to data loss and considerable economic losses. [0003] In order to prevent the hard disk from being damaged during vibration, the most...

Under normal circumstances, the distance between the head of the drive and the platter of the disk is very small, it is inevitable that there will be shaking and bumps during the moving process, and when the disk is in working condition, the head is easy to touch the disk, thus Damage the magnetic head, and in severe cases, it will scratch the disk and destroy the recorded data in the magnetic medium. This phenomenon is called "head collision". Once this happens, it will lead to data loss and considerable economic losses.

[0003] In order to prevent the hard disk from being damaged during vibration, the most common method is to set the operating system to enter the standby state, and it takes half a minute from the working state to the standby state and then back to the working state from the standby state. Devices, such as optical drives, hard drives, display screens, etc., and the frequent power-off and power-on of display screens with relatively high market prices will shorten their lifespan
