关于520硬盘的相关信息--数据恢复必备知识有些高端存储设备，硬盘格式化成每个扇区520字节，这种硬盘接到Windows机器时，操作系统启动非常慢，等到系统起来以后，才磁盘管理中能看到硬盘型号等信息。当用数据恢复工具或者磁盘镜像工具对硬盘进行读取的时候，返回错误信息，硬盘上的任何数据都没办法读，这就是我们常说的“非标硬盘”。关于非标硬盘的镜像工具，经过多年的摸索，达思工程师覃廷良在几年前联合补天王老师率先研发出windows平台下对520字节硬盘的镜像工具。达思目前正在把工具产品化。关于非标硬盘的详细信息，可以参考阅读国外一篇文章，没有精力翻译，感兴趣的可以看看。White Papers...........................................................................................................High Data Integrity on SATA White Paper (August 2005) Cost-Effective SATA Solutions Meet the Reliability Demands for Enterprise Storage Applications IntroductionThe demand for inexpensive, high-capacity storage media is growing at a phenomenal pace. Storage Managers feel the need for reliable and cheaper storage solutions more than ever. Traditionally, the vast majority of Just a Bunch of Disks (JBODs) shipped into enterprise storage applications are based on Fibre Channel (FC) technology. They are built on Fibre Channel Arbitrated Loop (FC-AL) infrastructure, use FC connectivity to Redundant Array of Independent Disks (RAID) controllers and rely on high-priced, dual-ported FC disk drives. These JBODs provide high performance, reliability and availability, but at a high Total Cost of Ownership. Basically, a cost barrier prohibits the use of expensive FC disk drives in all but the most critical enterprise applications. Sierra Logic’s innovative Silicon Storage family of controllers breaks through this cost barrier by enabling the use of lower-cost Serial ATA (SATA) disk drives in integrated storage solutions that leverage Fibre Channel as the connectivity to the RAID controller and between JBODs. Also, the Silicon Storage controllers increase storage system availability, functionality and performance with little modification to existing storage system firmware. The result is a cost-effective, versatile, scalable and transparent solution that justifies moving high performance RAID, Massive Array of Idle Disks (MAID), Network Application Support (NAS) and disk-based backup
