1. 概述
复制代码 代码如下:[root@centos6 ~]# fdisk /dev/sdc WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u'). Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-2088, default 1): Using default value 1 Last cylinder, +cylinders or +size{K,M,G} (1-2088, default 2088): Using default value 2088 Command (m for help): p Disk /dev/sdc: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xa1c3a1c3 Device Boot Start End Blocks Id System /dev/sdc1 1 2088 16771828+ 83 Linux 在完成之前，我们必须设置启动标志和分区系统ID，分区系统ID必须是WINDOWS的，ID值为 7. 复制代码 代码如下:Command (m for help): A Partition number (1-4): 1 Command (m for help): t Selected partition 1 Hex code (type L to list codes): 7 Changed system type of partition 1 to 7 (HPFS/NTFS) Command (m for help): p Disk /dev/sdc: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xa1c3a1c3 Device Boot Start End Blocks Id System /dev/sdc1 * 1 2088 16771828+ 7 HPFS/NTFS Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. = 复制MBR = 为了让新盘能够引导, 我们必须从Master Boot Record (MBR) 复制引导代码到新的磁盘上 MBR 在磁盘的第一个扇区,由3部分组成: 复制代码 代码如下:Boot Code (446 bytes) Partition Table (64 bytes) Boot Code Signature = 55aa (2 bytes) 我们只需要复制引导代码，起始的 446 bytes. 使用dd工具来复制： 复制代码 代码如下:# dd if=/dev/sdb of=/dev/sdc bs=446 count=1 1+0 records in 1+0 records out 446 bytes transferred in 0.026312 seconds (16950 bytes/sec) = 复制分区 = 下一步任务就是将文件系统从一个盘复制到另一个盘上.在这里我们使用 ntfsclone 工具来复制 NTFS 文件系统 复制代码 代码如下:[root@centos6 ~]# ntfsclone --overwrite /dev/sdc1 /dev/sdb1</p> <p> ntfsclone v2013.1.13 (libntfs-3g) NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 10725732352 bytes (10726 MB) Current device size: 10725732864 bytes (10726 MB) Scanning volume ... 100.00 percent completed Accounting clusters ... Space in use : 7565 MB (70.5%) Cloning NTFS ... 100.00 percent completed Syncing ... 如果在源盘上有坏的扇区，则需要添加 --rescue 选项 复制代码 代码如下:# ntfsclone --rescue --overwrite /dev/sdc1 /dev/sdb1 注意： 源盘 是 最后一个参数(/dev/sdb1)
复制代码 代码如下:[root@centos6 ~]# ntfsresize /dev/sdc1</p> <p> ntfsresize v2013.1.13 (libntfs-3g) Device name : /dev/sdc1 NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 10725732864 bytes (10726 MB) Current device size: 17174352384 bytes (17175 MB) New volume size : 17174348288 bytes (17175 MB) Checking filesystem consistency ... 100.00 percent completed Accounting clusters ...
