Disk Scan

In order to completely analyze data structure on an object, it must be scanned. Any object on the Drives panel can be scanned. In addition, you may create a region to scan only a part of an object. The Regions topic explains how to create and work with regions . Scan is also greatly improves estimations for chances of successful file recovery .

You may select scan area and some other scan parameters. Scan information may be saved to a file and later this file may be opened.

Attention: Scanning large areas may be a very lengthy process!

NEVER TRY TO SAVE SCAN INFORMATION ON THE OBJECT BEING SCANNED!!!

Or you may obtain unpredictable results and lose all your data.

To scan an object

1	Select an object on the R-Linux 's Drives panel

2	Click the Scan button

Other ways to start scan

3	Specify the required parameters on the Scan dialog box and click the Scan button

Scan options

Disk Size:	Shows the size of the object to be scanned
Start:	Sets the start point of the area to be scanned.
Size:	Sets the size of the area to be scanned.
Numbers in these fields can be in bytes or sectors. See the Data Formats and Multipliers topic for more details on data formats.
File Systems:	Specifies the file systems which objects are to be searched for. Current version supports: Ext2/3/4FS.
Extra search for Known File Types	Enables search for Known File Types .
Save scan Info to File:	If this checkbox is selected, R-Linux will save scan information to a specified file. Later this file may be opened. Please note, that this option does not save actual disk data, only information on disk data structure gathered during disk scan.

Known File Types : While scanning, R-Linux can recognize to which particular file type the data belong. Using such information, R-Linux can obtain more information about data/file structure on the object being scanned. By default, R-Linux tries to recognize all supported file types, greatly increasing time required for the scan. You may reduce it by selecting only those file types that you need. Click the Known File Types... button and select the required file types on the File Types dialog box.

>	R-Linux starts scanning the object, and its panel will show information about new found objects:

The Log pane will show scan progress. Scan may be stopped by clicking the Stop button on the tab. Later the scan process may be resumed with different scan parameters. Some scan parameters may also be changed during the scan process. Click the Options button and change them on the Scanning dialog box .

R-Linux Main panel

You may see which file object(s) is/are on a particular disk part. Click the corresponding rectangle on the Scan Information pane and view the information on the Scan Information dialog box.

Scan Information dialog box

Select the file object and click Open in Hex Viewer to view the file object in the Text/Hexadecimal Viewer .

When an object is scanned, a number of Recognized partitions will appear. R-Linux shows them in different colors depending on which elements of the partition have been found.

	An existing partition
	An existing partition after disk scan
	Both boot records and file entries are found for this partition
	Only file entries are found for this partition
	Only boot records are found for this partition
	A deleted partition
	Empty space on the object
	Files that have been found using scan for known file types .

Although such recognized partitions are virtual objects, files can be searched for and recovered from recognized partitions as from real partitions using Basic File Recovery .

To see the information about a newly found object, simply click it on the Drives panel. Click this link to see the information about the object Recognized5 on the partition: .

When an object in a scanned drive is selected, R‑Linux shows the scanned area of the object.

Object's scanned area

All scanned information may be deleted on the context menu for a scanned object.

Scan information may be saved in a file. Previously saved scan information may be loaded. This can be done on the Drive or context menu for a selected object.

Resuming incomplete scans or scanning the object with different parameters

You may resume the scan of an incompletely scanned object or rescan the already scanned object with different parameters. The Scan dialog will be a little bit different in this case.

Scan dialog box for incomplete scans

You may rescan the entire disk, scan unscanned areas, or scan an explicitly specified area.

Scan of multiple areas

You may simultaneously scan several successive or overlapping areas. Click the Advanced button, specify an offset and size for a new area to scan on the Advanced Scan dialog box and click the Add button. You may specify and add several scan areas. You may select which areas should be scanned. Selected scan areas can be merged. Right-click a necessary area and select either Merge Down , Merge Down All , and Merge Selected . You may also select/unselect unscanned areas.

Advanced Scan dialog box

R-Linux accumulates the information from successive scans and keeps track of changes in this information obtained from different scans.

Managing scan information

Scan information may be saved to a file. Previously saved scan information may be loaded.

To save scan information

1	Select an object on the R-Linux Drives panel

2	Select Save Scan Information on the Drive or context menu and save the scan information in a file

The default file extension is *.scn.

To load scan information

1	Select an object on the R-Linux Drives panel

2	Select Open Scan Information on the Drive or context menu and select the required file with the scan information
