1.为了顺利安装testdisk 工具,安装开发四个组包（正确的配制yum）。yum groupinstall " Development Libraries " -y，注意一定要加引号。yum groupinstall " Development Tools " -yyum groupinstall " Legacy Software Development " -yyum groupinstall " X Software Development " -y注：对应成中文就是:Development Libraries 开发库; Development Tools 开发工具;Legacy Software Development 老的软件开发; X Software Development X软件开发;查看分区表。发现少了一个主分区。2.安装testdisk[root@localhost ~]# tar -jxvf testdisk-6.8.tar.bz2 [root@localhost ~]# cd testdisk-6.83.查看configure帮助[root@localhost testdisk-6.8]# ./configure --help |less预编译。 [root@localhost testdisk-6.8]# ./configure --prefix=/usr/local/sbin //指明安装路径。4.编译。产生头文件，库文件，可执行文件，说明文件。[root@localhost testdisk-6.8]# make && make install启动 testdisk： [root@localhost sbin]# lsman photorec sbin share testdisk testdisk.log[root@localhost sbin]# ./testdisk第一页屏幕要求选择如何处理记录信息 第二页要求选择磁盘： TestDisk is free software, andcomes with ABSOLUTELY NO WARRANTY.Select a media (use Arrow keys, then press Enter):Disk /dev/hdc - 3005 MB / 2866 MiB (RO)Disk /dev/sda - 21 GB / 19 GiB[Proceed ] [ Quit ]第三页选择分区表类型，一般都是 Intel/PC： Disk /dev/sda - 21 GB / 19 GiBPlease select the partition table type, press Enter when done.[Intel ] Intel/PC partition[Mac ] Apple partition map[None ] Non partitioned media[Sun ] Sun Solaris partition[XBox ] XBox partition[Return ] Return to disk selectionNote: Do NOT select 'None' for media with only a single partition.

'Analyse'process may give some warnings if it thinks the logical geometry is mismatched.列出现有的分区表内容，并提示继续还是备份，这里只有一个分区，实际上另外一个 Linux 分区被删了...所以 1661 之前那些空间就是寻找的目标： Disk /dev/sda - 21 GB / 19 GiB - CHS 2610 255 63Current partition structure: Partition Start End Size in sectors 1 * Linux 0 1 1 130 254 63 2104452 [/boot] 3 P Linux Swap 1661 0 1 1791 254 63 2104515Should TestDisk search for partition created under Vista ?
