4KB hard disk sector Vista compatible patch official download

Microsoft sometimes releases multiple regular update patches as the monthly security patch is upgraded to address a variety of non-security issues. Some of these patches will be placed in the official website download center and automatically pushed through WindowsUpdate, and some are only Hotfix hot fixes, which need to be requested by users. This month we got the SVG vector graphics rendering correction patch KB2563227 through WindowsUpdate, and introduced the blue screen patch KB2528641, DVD burning disk reading patch KB2566584, USB device performance improvement patch KB2581464, and now look at the 4KB sector technology & ldquo Advanced format "Advanced Format compatibility patch.
Advanced format is a new hard disk sector technology introduced by hard disk manufacturers from the end of 2009. The physical sector capacity of the hard disk is expanded from 512 Bytes to 4 KB, which can obtain larger format capacity and significantly improve the hard disk. Reliability. In order to maintain wider compatibility, the 4KB sector hard disk still retains a 512Byte logical addressing interface, called "512-byte emulation disks" or "512e".
Of course, this requires both the operating system and the application software to natively support 4KB sector capacity write operations, otherwise additional work must be done, which in turn affects performance and reliability. Windows Vista/7 and the corresponding server system WindowsServer 2008/2008 R2 can natively support 4KB sectors in advanced format, but there are still some compatibility issues with the previous generation system WindowsVista/Server 2008, so Microsoft released a hot fix KB2553708.
According to the knowledge base article, the patch fixes three aspects: the first involves the storage driver model Storport (corresponding to the file Storport.sys); the second involves the file system related task utility Fsutil (corresponding to the file Fsutil. Exe), able to output new Bytes Per Physical Sector, which is "512" on the traditional 512-byte hard disk, and "4096" in the new 4KB sector hard disk; Report on the physical sector capacity of various storage devices.
