8.2.5 Search

The Search menu lets you search a disk for a line and to go to a disk sector according to its absolute

offset.

A search line can be set both as char and as numeric (hexadecimal) values. During a search, you can

ignore letter case as well as search for a given line at a given offset inside the sector.

The disk data is interpreted according to the encoding selected. If you selected a search mode

without a matching case letter, both the case and elements above the characters will be ignored.

After the search process is finished, the current position will be moved to where a line was found, or

will remain the same if no lines were found. You can search for the next line by pressing the F3 key.

You can go to the necessary sector according to its absolute offset, by selecting the Go to menu item

(or by pressing the Alt+P key combination).

The transition is performed by entering an absolute sector offset, or by entering cylinder, head and

sector numbers. The listed parameters are bound by this expression:

(CYL x HDS + HD) x SPT + SEC – 1,

where CYL, HD and SEC are cylinder, head and sector numbers in the CHS coordinates (Cylinder –

Head – Sector); HDS is the number of heads per disk and SPT is the number of heads per track.

You can return to a sector from another one by selecting the Back item in the Search menu (or by

pressing the Ctrl + B key combination).

8.2.6 Usage examples

This section describes how to use Acronis Disk Editor for the most common scenarios.

8.2.6.1 Protecting and restoring MBR

This example applies to basic disks whose partitioning scheme is MBR.

The master boot record (MBR) is located in the first sector of the hard disk and stores information

about the hard disk partitioning and code that is loaded with BIOS. Information stored in the MBR is

crucial for the machine booting.

If the MBR code is corrupted due to boot sector viruses or human error, the machine becomes

unbootable and you cannot access the data stored on the hard disks.

By having the MBR code copy saved in a safe place, you will protect your machine against such

disasters. Even if your machine fails to boot normally, you can boot it by using bootable media

created with Acronis Bootable Media Builder (p. 49). Under bootable media, you can start Acronis

Disk Editor and restore the MBR from a previously saved copy. Thus, the machine bootability will be

completely restored.

The following describes how you can save the MBR code copy and restore it in case failure.

Step 1. Saving MBR

1. In Acronis Disk Director right-click the disk whose MBR code you need to save, and then click

Edit.

2. In Acronis Disk Editor press F2 key to switch to the Hex view mode.
