我们大多数人都知道主引导记录^{(Master Boot Record)}( MBR ) 是一种特殊类型的引导扇区，位于存储设备的开头，它告诉您的计算机在启动时要做什么。它包含引导计算机系统所必需的重要引导信息。此外，如果您的机器上安装了多个操作系统，有时病毒或其他操作系统设置会覆盖MBR/Boot 扇区^(Sectors)，从而难以启动首选操作系统。

如果由于某种原因MBR由于恶意软件攻击或任何其他原因而损坏，您可能会发现硬盘驱动器上的数据将无法挽回地丢失。因此，备份MBR是一个好主意。虽然只有在MBR^(MBR)损坏或 PC 设置在不知不觉中发生更改（例如更改硬盘分区或安装或卸载操作系统）时才可能需要恢复，但应始终准备好备份。

如果您的MBR损坏，您可以从随身携带的备份中快速恢复它。与MBR Backup一样，  HDHacker是另一个帮助您快速备份MBR的免费软件。

Back up & Restore Boot Sector & MBR with HDHacker

Most of us are awаre that the Master Boоt Record (MBR) is a special type of bооt sector, placed at the beginning of the storage device, that tells your computer what to dо when it starts. It contains impоrtant boot information which is neсessаry for bootіng a comрuter system. Also, somеtimes viruses or other OS setup can overwrite the MBR/Boot Sectors if you have more than single OS installed оn your machine, making it diffiсult to start-up favored OS.

If for some reason the MBR gets corrupted due to a malware attack or any other reason, you may find that the data on your hard drive will be irretrievably lost. It is, therefore, a good idea to back up the MBR. Although the need to restore may arise only when the MBR is corrupted or when the setup of the PC changes unknowingly like for instance, the hard drive partitions are changed or an OS is installed or uninstalled, one should always have a back up ready.

If ever, your MBR gets corrupted you can restore it from a backup you have with you quickly. Like MBR Backup, HDHacker is another freeware that helps you in backing up MBR quickly.

HDHacker – Backup & Restore Boot Sector & MBR

HDHacker is a stand-alone micro-utility that saves, visualizes, and restores the MBR (from a physical drive), the Boot Sector (from a logical drive) or any specified sector from any disk (even removable disks). The program is an advanced hard drive tool for system administrators and advanced users only. Any improper use or misuse can lead to inaccessible hard drives and make your computer un-bootable.

It comes with a graphical user interface. HDHacker upon the launch, responds quickly and immediately displays sector information. All the user has to do is chose a drive (physical/logical) to operate, together with the first or custom sector. All the information displayed can be saved to the clipboard or written on a disk. In addition, you can save a sector to file (DAT format).

As mentioned earlier, it may be a good idea to back up the Boot Sector & MBR, because it can prove to be useful if ever some boot-sector virus or another OS setup, like Linux, were to overwrite, alter or corrupt the MBR/Boot Sectors, making it impossible to start-up your original operating system.
