分区表

The first difference is in the partition table of the MBR and is due to a disk size difference in the 4th partition.

第一差异在分区表的MBR和是由于磁盘大小不同，第四分区。

Partition table as a result of capacity constraints, FAT16 partition to support the bigger the disk capacity of each cluster is also greater, resulting in greater waste.

由于分区表容量的限制，FAT16支持的分区越大，磁盘上每个簇的容量也越大，造成的浪费也越大。

In my opinion, the simplest approach is: Normally, the hard drive to back up a partition table (not, to find a model with the same hard disk partition table can be), the event was to get rid of a hard disk, floppy disk with both fixed, it can be hard in the bios will set none, to start after the backup to restore the partition table back to the hard disk and then change the settings back from the new start, fdisk it.

我认为，最简单的办法是：在平时，将硬盘的分区表备份一个（没有的话，找一个与之相同型号的硬盘的分区表也可以），万一硬盘被干掉了，用软盘都起不动的话，可以在bios里将硬盘设为none，启动后，将分区表的备份恢复回去，然后将硬盘的设置改回来，从新启动，fdisk就可以了。

As the root user, when you use the format utility and select a disk to partition, a copy of the disk's partition table is read from the label on the disk into memory and is displayed as the current disk partition table.

当你使用format命令时，format将读取这个文件(/etc/format.dat )。这个文件是一个可用磁盘类型的表和一个预先定义的分区表的集合，你能用它来快速分区磁盘。

到这里，就已经将原先的windows的E盘（2501到5000柱面），那个/dev/sda6分成了三个区。现在如果保存分区操作后，再使用格式化工具创建文件系统后，原先的 2501到5000柱面上的数据将丢失。当然，我们不必担心，因为事先已经将文件复制到了其它的地方了。注意：现在有一个问题，看上面/dev/sda11 的尾柱面是 5000 ，而/dev/sda6的首柱面是5001 。一直到/dev/sda8 的首柱面都位于/dev/sda11的尾柱面之后。也就是说它们的物理位置在后面，但分区编号在前面。为改变这一状况，有一个简易的方法。就是先删紧靠 5000柱面之后的一个分区，然后立即按默认首柱面和尾柱面进行分配，在重建分区表的时候注意把分区的系统标识也改也原先的（因为 Linux的fdisk中默认的新建的分区系统标识为id为83。

Commonly used format for high-level "quick format" is only to reset the hard disk partition table, even the "complete format", it was hard reset the partition table in addition to all sectors to re-nulling.

对于常用的高级格式化，"快速格式化"仅仅是重置硬盘分区表，即使是"完全格式化"，也不过是在重置硬盘分区表之外，把所有扇区重新置零。

hand to restore the partition table is a relatively reliable method to restore the use of this method must first master the strategy division of the hard disk partition, partition the data records of the location, area of the recording format of data, area data of the inter-relationship between as well as the partition table of the relevant knowledge group; winhex followed by the use of software to be able to deal with access to hard data on the sector, and in accordance with the results derived to deal with the loss of the partition information, and to achieve the restoration of the partition table.

手工恢复分区表是一种比较可靠的恢复方法，使用这一方法必须首先掌握硬盘分区的划分策略、分区数据的记录位置、分区数据的记录格式、分区数据之间的相互关系以及分区表组的相关知识；其次要能够使用winhex软件，去处理访问硬盘有关扇区的数据，并根据处理结果来推导出丢失的分区信息，进而实现分区表的恢复。

For partitioned tables, table locks can be acquired at both the table and the subpartition level.

对于分区表来说，表级锁既可以针对整个表，也可以只针对某个分区。

当查找用-id创建的映像文件时，会在分区表中看到未分区的空间和扩展分区。
