西部数据(WD)硬盘4K扇区技术及分区对齐工具简介

文章编号:44740     2012-1-31 14:55:12
关于西数(WD)硬盘4K/扇区新技术
一张硬盘磁片,并不是所有的扇区都在用来存储数据,还有部分扇区是用来干些别的事的。传统的扇区分割机制中,每512byte的数据之间,需要间隔一个同步/分隔(Sync/DAM)区域和一个ECC错误校验区域。而在“先进格式”模式下,每4K为一个扇区,相当于把之前的8个扇区合而为一,只需要一个同步/分隔区域和一个容量稍大的ECC校验区,采用advanced format技术每4K的数据记录扇区只需要一个Sync/DAM和ECC区,而传统的需要8个。这节省出来的7个原本用于Sync/DAM和ECC的扇区就可以用来储存更多的数据。 针对安装Windows XP或其他较老版本Windows 操作系统用户,其通过系统自带的或其他硬盘分区工具格式化出来的硬盘分区,往往不是4K对齐的,此时可能存在较低版本系统、软件无法充分发挥新技术的优势现象,所以为了使操作系统、软件更好配合4K/扇区新硬盘性能的发挥,就需要进行先进的格式化。对比测试发现,Windows系统分区在没有进行硬盘4K扇区对齐的情况下,硬盘拷贝速度可能会比优化过的慢百分之十几(最差值)。
更多关于西数(WD)4K/扇区硬盘技术信息,请访问:http://www.wdc.com/en/

如何查看硬盘是否4K分区对齐
在Windows XP\\VISTA\\7系统下,点击“开始”,“运行”,输入“MSINFO32”,点击“确定”,出现如下显示的界面,依次点击“组件(components)/存储(storage)/磁盘(disks)”,查看下图彩色方框显示的分区的地址数值(Value),如果不能被4096整除,则为非对齐的情况,需要使用西数(WD)提供的WD Align Utility或其他工具来做成分区对齐,以提升硬盘的读写速度。如果能被4096整除,则为对齐的情况,不再需要相应分区对齐工具进一步操作。



针对上图情形:
第一分区起始偏移 32,256/4096=7.875                                 没有实现4K对齐
第二分区起始偏移 31,461,696,000/4096=7681078.125          没有实现4K对齐
第三分区起始偏移 156,847,864,320/4096=38292935.6250     没有实现4K对齐

备注:
联想预装Windows操作系统且采用西数(WD)4K/扇区新技术机型在出厂前已经进行4K对齐操作。以上4K未对齐情形,只出现在客户自行安装Windows XP等Windows系统情形,和联想产品无关。 如何查看硬盘是否为西数(WD)且支持4K/扇区技术,可以下载、安装其分区对齐WD Align Utility软件进行确认(如果不满足上述其中之一条件,该软件可能不会继续运行)。

Steven Spielberg's epic adaptation of the novel and Broadway play War Horse had its world premiere Sunday night at Lincoln Center's Avery Hall, just feet from where the theatrical production is continuing its blockbuster run. Spielberg was on hand before the film to introduce the vast majority of the film's large ensemble, including the film's three big up-and-comers, 21-year-old Englishman Jeremy Irvine, 21-year-old German David Kross and 15-year-old Frenchwoman Celine Buckens, as well as veterans David Thewlis (who also stars in The Lady) and Emily Watson (who was twice nominated for the best actress Oscar in the 1990s). Regretfully, Spielberg noted, the 18 horses that played the title character "Joey" -- the true star of the film -- were unable to attend.

She also had  to quickly learn the ropes regarding the proper terms to describe her character in the press. Last year she caught flak for describing her role as a “tranny” in an interview with BlackBook magazine.

On the scene in which she gives some bad news  "To cry wasn't hard -- I'm very in touch with my emotional side; I don't know why. But to cry wasn't hard because the words evoked the emotion. What was fun about that scene was to not cry, to try and hold it in. I know that sounds weird, but that's almost more difficult sometimes than actually crying... It was a beautiful moment for me because I really got to express her in the way I wanted without the feeling of being rushed, or annoying, or anyone judging me."

    解决方法:西数硬盘的下载西数wd align软件。 WD align下载地址:http://dl.dbank.com/c0pegwpbtu(注:如果你在西数官网注册你的硬盘产品,会发现下边就有提示要你安装wd align软件检测扇区是否对齐。)软件使用很简单,相信会点分区知识的都会用。有这个问题的可以去试下。 日立硬盘的朋友请下载Hitachi Align Tool。 Hitachi Align Tool下载地址: http://www.hitachigst.com/hdd/support/downloads/AcronisAlignTool_s_cs.exe 使用方法大概与WD Align相同,因为没有日立硬盘,所以没方法,见谅。 希捷的据说不对齐没事,所以官网没提供对齐工具,最好还是对齐吧。非官方通用对齐工具。 Paragon Alignment Tool :http://u.115.com/file/clom4fe2 借用风之林榆的地址,谢谢了。 东芝的官网也提供了对齐工具,不过我没用过,把地址贴出来大家研究一下。也是Paragon Alignment Tool,不过挂上了官方名称叫AF Drive Alignment Tool: http://cdaweb01.tacp.toshiba.com/support/utilities/PAT_Toshiba_edition_ea.exe 以上三个工具全部都是无损对齐工具。不过强烈建议备份分区表和磁盘重要数据!!因为对齐过程会修改分区表,如果断电数据可不好找回来。 鉴于我的是WD的,补充上WD Align使用方法。Hitachi Align Tool使用方法类似.
