硬盘作为存储数据的一个利器,在高速发展的存储器工业中,硬盘单碟密度越来越高,容量越来越快……保护数据的完整性就越业越显得重要了,因为硬盘的主要目的就是存储数据,保护数据不丢失。伴随着每一项存储新技术的推出,新的数据保护技术也在不断出现。 1、S.M.A.R.T S.M.A.R.T(Self-Monitoring,Analysis and Reporting Technology)自监测、分析和报告技术出现了,它在ATA-3标准中被正式确立,而所有硬盘厂商也都提供对它的支持,S.M.A.R.T技术可以监测磁头、磁盘、马达、电路等,由硬盘的监测电路和主机上的监测软件对被监测对象的动作情况与历史记录和预设的安全值进行分析、比较,当出现安全值范围以外的情况时,能够自动向用户发出警告。而更先进的技术还可以自动降低硬盘的运行速度,
As a tool to store data, the hard disk is becoming more and more important in the fast-growing memory industry due to the ever-increasing density and increasing capacity of hard disks. The more important it is to protect the integrity of data, since the main purpose of a hard disk Is to store data, data protection is not lost. With the introduction of every new storage technology, new data protection technologies are also emerging. 1, SMART SMART (Self-Monitoring, Analysis and Reporting Technology) Self-monitoring, analysis and reporting technology has emerged, it is formally established in the ATA-3 standard, and all hard disk manufacturers also provide support for it, SMART technology can Monitor the head, disk, motor, circuit, etc., by the hard disk monitoring circuit and the host monitoring software on the monitored object action and historical records and the default value of security analysis, comparison, when the situation outside the safety value range When the user can automatically issue a warning. The more advanced technology can also automatically reduce the operating speed of the hard disk,
