Method for protecting data of memory mechanism

Abstract

The invention provides a data protection method of a storage device, which is applied to a computer unit. The data protection method includes the following steps: an interrupt management program of the system acquires information of error pattern and address of an error chunk in a first storage device by a hardware control device, and the information is stored into a second storage device; the information of the error pattern and the error chunk of the first storage device is read by a drive service program from the second storage device; the drive service program informs an operating system to search a chunk which can be accessed normally and not destroyed in the first storage device, and the chunk is set as a default chunk; the drive service program transmits the information of the address of the error chunk in the first storage device to the operating system, thereby the operating system copies the data of the error chunk in the first storage device to the default chunk, so that the using capacity of the storage device can be increased, and the reliability of the computer unit can be improved.

Description

technical field [0001] The invention relates to a data protection method of a storage device, and in more detail, relates to a data backup method applied to a memory in a computer device with a memory. Background technique [0002] With the prosperity of the economy and the progress of science and technology, the use of various computers and servers is becoming more and more common. However, memory plays an important role in computers and servers, and its impact on system performance is playing a more critical role than before. As long as the memory An error of more than 1 bit will cause data error or loss, which will cause great trouble to consumers. [0003] The existing technology uses three modes of standard mode (Standard), spare mode (Spare) and mirror mode (Mirror) to cooperate with the hardware control device to operate DIMM (Dual In-line Memory Module) and perform data backup actions. The above three technologies are The technology commonly used in the industry is ...

[0002] With the prosperity of the economy and the progress of science and technology, the use of various computers and servers is becoming more and more common. However, memory plays an important role in computers and servers, and its impact on system performance is playing a more critical role than before. As long as the memory An error of more than 1 bit will cause data error or loss, causing great trouble to consumers

[0003] The existing technology uses three modes of standard mode (Standard), spare mode (Spare) and mirror mode (Mirror) to cooperate with the hardware control device to operate DIMM (Dual In-line Memory Module) and perform data backup actions. The above three technologies are The technology commonly used in the industry is a well-known technology for those who are familiar with this technical field, so it will not be described in detail. However, although the backup mode and the mirror mode have high reliability, they need to occupy a set of memory with the same size for Backup, so the design can only use half of the storage capacity, resulting in a waste of money and storage

[0004] Therefore, how to avoid retaining a group of memory with the same size for the purpose of backing up the data of the memory, resulting in the usage capacity of the memory being only half of the original, causing the memory to be wasted, is an urgent problem to be solved at present.
