硬盘分区

A hard disk has an MBR, this is because a hard disk can have multiple partitions and any one of them can be bootable.

硬盘有一个MBR，这是因为一个硬盘可以有多个分区，并且其中的任何一个分区都可以是可启动的。

Data Recovery: hard drive data recovery, hard drive repair, hard disk Bad Track, Area repair.

数据恢复：硬盘数据恢复，维修硬盘，硬盘坏道、分区修复。

However, this district has its format shortcomings, first of all, the format is fat32 disk partition, file allocation table as a result of the expansion of the use of running faster than fat16 format hard drive partition slower; In addition, as a result of the system and some dos Early applications of this district do not support the format, so this geographical format, you can not use the old dos operating system and the application of some old software.

但是，这种分区格式也有它的缺点，首先是采用fat32格式分区的磁盘，由于文件分配表的扩大，运行速度比采用fat16格式分区的硬盘要慢；另外，由于dos系统和某些早期的应用软件不支持这种分区格式，所以采用这种分区格式后，就无法再使用老的dos操作系统和某些旧的应用软件了。

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。

The design of the partition system in an Apple system is a nice balance between the complexity of DOS-based partitions and the limited number of partitions that we will see in the BSD disk labels.

苹果系统的分区设计是在基于DOS分区的复杂性和我们会在BSD硬盘标签里看到的有限的分区编号之间的一个完美的平衡。

We see the signature value of 0x504d in bytes 0 to 1 and the number of partitions in bytes 4 to 7, which is 10 (0x0000000a). Bytes 8 to 11 show us that the first sector of the disk is the starting sector for this partition and that its size is 63 sectors (0x3f). The name of the partition is "Apple," and the type of partition is "Apple_partition_map." Bytes 88 to 91 show that no flags for this partition are set.

我们可以看到0-1字节处签名值为0x504d，4-7字节处的分区总数为10，8-11字节处表示硬盘的第一扇区是该分区的起始扇区，它的大小为63扇区（0x3f），分区名称为"Apple"，分区类型为"Apple partition map"，88-91字节处显示该分区无设置标志。

The default setting for the Ubuntu partitioner is to delete everything on the first hard drive and start from scratch.

Ubuntu安装程序的分区工具的默认设置是删除您的第一张硬盘中的所有分区并在空白的硬盘中分区。

Zero once the damaged track will be the primary boot hard drive and the partition table information will be seriously damaged, resulting in the hard disk can not boot. 0 tracks damaged judge: System self-test pass, but the boot partition C disc lost or directory is missing, there are laws of the hard disk "... creak ... creak" seek the sound of running SCANDISK scanning C disk, in the first cluster a red "B", or can not find Fdisk the hard disk, DM died in the 0 track, the track such a situation that is zero damage!

零磁道一旦受损，将使硬盘的主引导程序和分区表信息将遭到严重破坏，从而导致硬盘无法引导。0磁道损坏判断：系统自检能通过，但启动时，分区丢失或者C盘目录丢失，硬盘出现有规律的"咯吱……咯吱"的寻道声，运行SCANDISK扫描C盘，在第一簇出现一个红色的"B"，或者Fdisk找不到硬盘、DM死在0磁道上，此种情况即为零磁道损坏！

Hard Drive Size / Geometry: Under the Windows NT family (Windows NT, 2000, XP, and future versions), this uses the number of cylinders, heads, sectors, and other details of the first physical hard drive, and cannot be changed except by changing the hard drive type in the system's BIOS (which almost always necessitates repartitioning, reformatting, and reinstalling the operating system as well).

硬盘大小/几何：在winnt家族下(Windows NT， 2000， XP， and future versions)，，这个选项使用第一物理硬盘的柱面，磁头，扇区数和其他细节，不能被改变除非在系统BIOS里改变硬盘类型（几乎总是同时需要重新分区、重新格式化、重新安装操作系统）。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
