Backup and Restore Boot Sector and MBR with HDHacker

Most of us are aware that the Master Boot Record (MBR) is a special type of boot sector that is at the beginning of the storage medium and tells your computer what to do when it starts. It contains important start-up information needed to start a computer system. In addition, sometimes viruses or other operating system settings can overwrite MBR/boot sectors if you have more than one operating system installed on your computer, making it difficult to boot the preferred operating system.

If the MBR is damaged for any reason by a malicious attack or for any other reason, you may find that the data on your hard disk is irretrievably lost. It is therefore a good idea to support the MBR. Although the need for recovery can only occur if the MBR is corrupted or if the PC configuration changes without knowing it, for example if the hard disk partitions are changed or if an operating system is installed or uninstalled, you should always have a backup ready.

If your MBR is damaged, you can quickly restore it from a backup you have with you. Like MBR Backup, HDHacker is another freeware that helps you back up MBR quickly.

HDHacker is a standalone firmware that stores, views and restores the MBR (from a physical disk), boot sector (from a logical disk) or any sector from any disk (including removable disks). The program is an advanced hard disk tool for system administrators and advanced users. Improper or incorrect use can lead to inaccessible hard drives and render your computer unusable.

It comes with a graphical user interface. HDHacker reacts quickly to start-up and immediately displays industry information. The user only needs to select a drive (physical/logical) to work with the first sector or user-defined sector. All information displayed can be saved to the clipboard or written to a floppy disk. You can also save a sector in a file (DAT format).

As mentioned above, backing up the boot sector and MBR can be a good idea, as it may prove useful if a boot sector virus or other operating system, such as Linux, overwrites, modifies or damages the MBR/boot sectors, making it impossible to boot the original operating system.
