Embodiment 1

[0084] Please refer to figure 2 , which shows a schematic structural diagram of a solid-state hard disk provided in Embodiment 1 of the present invention, the solid-state hard disk may include a first storage area 110 and a second storage area 120;

[0085] The first storage area 110 is a protected area, and the first storage area 110 is used to store backed up system data;

[0086] The second storage area 120 is a protection area, and the second storage area 120 is used to store a mapping table corresponding to the backed up system data, and the mapping table includes the correspondence between the logical disk address and the physical disk address corresponding to the backed up system data Correspondence;

[0087] The protected area is a read-only area that cannot be erased.

[0088] Preferably, the first storage area 110 and the second storage area 120 are two or more groups, and the backed-up system data and mapping tables stored in each group correspond to different ba...

Embodiment 2

[0093] Please refer to image 3 , which shows the method flow chart of the system restoration method provided in Embodiment 2 of the present invention. The system restoration method can be used in an electronic device including the solid-state hard disk provided in Embodiment 1. The system restoration method may include:

[0094] Step 201, receiving a system recovery signal;

[0095] When the system of the electronic device used by the user crashes, the user can send a system recovery signal to the electronic device, and correspondingly, the electronic device can receive the system recovery signal. In actual implementation, the electronic device may enter a restart state after receiving the system recovery signal, which is not limited in this embodiment, and restarting the electronic device is taken as an example.

[0096] Step 202, read the mapping table stored in the second storage area of ​​the solid state disk according to the system recovery signal;

[0097] When the el...

Embodiment 3

[0105] Please refer to Figure 4 , which shows the method flow chart of the system recovery method provided in Embodiment 3 of the present invention. The system recovery method can be used in the electronic device including the solid-state hard disk described in Embodiment 1. The system recovery method can include:

[0106] Step 301, receiving a system backup signal;

[0107] During the user's use of the electronic device, in order to restore the electronic device to a certain current system state, the user may request to back up the system data in the electronic device, and the electronic device may receive a system backup signal accordingly.

[0108] For example, in order to restore the electronic equipment to the state when the electronic equipment leaves the factory when the system crashes, the user can send a system backup signal for backing up the factory system data. Correspondingly, the electronic equipment can receive the system backup signal .

[0109] Step 302: Ba...

Abstract

The invention belongs to the technical field of computers, and discloses a system recovery method, a system recovery device, a solid state disk and electronic equipment. The system recovery method includes: receiving a system recovery signal; reading a mapping table stored in a second memory region of the solid state disk according to the system recovery signal, wherein the mapping table includes corresponding relation between a physical disk address and a logical disk address corresponding to backed-up system data; reading the backed-up system data stored in a first memory region of the solid state disk according to the mapping table; loading the read-out backed-up system data. The problems of long system recovery time and waste of disk space in the prior art are solved; system recovery can be realized only by reading the mapping table stored in the solid state disk and reading and operating the backed-up system data according to the mapping table, so that the effect of short system recovery time is achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a system recovery method, device, solid-state hard disk and electronic equipment. Background technique [0002] An electronic device such as a tablet computer or a desktop computer requires an operating system to be installed in order to operate normally. However, when the user accidentally deletes the system files in the electronic device or the system is infected with a virus, the operating system in the electronic device will be in a crash state and cannot be used any longer, so the user needs to restore the system of the electronic device at this time. [0003] In an electronic device using a traditional mechanical hard disk, an existing system recovery method includes: first, setting a hidden partition in the mechanical hard disk, and storing backup system data in the hidden partition. When the user needs to restore the system of the electronic device, the electronic devi...
