Disk Scan

Top  Previous  Next

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.

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!


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

To scan an object

1 Select an object on the R-Studio's Drives panel
2 Click the Scan button

Click to expand/collapse Other ways to start scan

· Right-click the selected disk and select Scan on the shortcut menu,


· Select Scan on the Drive menu
3 Specify the required parameters on the Scan dialog box and click the Scan button

Scan dialog box

Click to expand/collapse Scan options

Disk Size:

Shows the size of the object to be scanned


Sets the start point of the area to be scanned.


Sets the size of the area to be scanned.

Numbers in these fields can be in bytes or sectors. If no letters are after the numbers, R-Studio assumes the numbers are in bytes.

See Data Formats for more details.

File Systems:

Specifies the file systems which objects are to be searched for.

Current version supports: FAT, NTFS, exFAT, Ext2/3/4FS, HFS, and UFS file systems.

Please note that if you need to scan an HFS, HFS+, or HFSX disk, always enable the Extra search for Known File Types option. This is very important because when files are being deleted on the HFS, HFS+, HFSX file systems, the computer completely removes all system information on them, and there is no way to recover the deleted files except by using the Extra Search for Known File Types option. See Data Recovery on HFS/HFS+ file system for details.

Extra search for Known File Types

Enables search for Known File Types.

Save scan Info to File:

If this checkbox is selected, R-Studio 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.

Simple view

If this option is selected, R-Studio will show only scan progress.

Detailed view

If this option is selected, R-Studio will show graphic representation on objects found during scan.


If this option is selected, R-Studio will not show the Scan Information tab during scan.



Starts scanning


Activates advanced scan options

Known File Types...

Selects file types that R-Studio will recognize during the disk scan.


Closes the dialog box


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

Known File Types: While scanning, R-Studio can recognize the data’s particular file type. Using such information, R-Studio can obtain more information about data/file structure on the object being scanned. By default, R-Studio tries to recognize the default list of supported file types specified on the Known File Types tab of the Settings panel, 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. These selections will be applied to that scan session only.

Note: Using scan for Known File Types, R-Studio can successfully recover only un-fragmented files.

You may also specify your own file types for scanning. See Customizing File Types for details. User-defined file types precede over built-in ones, if their definitions overlap.

You may set the defaults for known file types on the R-Studio Settings.

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

Click to expand/collapse R-Studio Main panel

Click the panel regions to learn their functions.

Stop (Esc) Delete (F8) Create virtual volume sets or RAIDs Create Region (F4) Create Image Open Image Scan Open Drive Files (F5) Refresh (Control+R) Connect to Remote

The Log pane will show scan progress. Scan may be stopped by clicking the Stop button on the toolbar. Later the scan process may be resumed with different scan parameters.

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.

Click to enlarge
Scan Information dialog box

Double-click an object to view/edit the file object in the Text/hexadecimal editor.

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

An existing logical disk or partition

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

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 logical disks 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 Recognized17 on the logical disk H:.

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

Multiple scans

If the selected object has been completely scanned, you may rescan it either completely or with new scan parameters. If the selected object has been scanned partially, you may scan the rest of the object, ignore the existing scan information and scan the entire object, or specify scan parameters manually.

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

You may make several scans of 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.

Click to enlarge
Advanced Scan dialog box

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-Studio Drives panel
2 Select Save Scan Information on the Drive or shortcut 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-Studio Drives panel
2 Select Open Scan Information on the Drive or shortcut menu and select the required file with the scan information

The default file extension is *.scn.

> The scan information will appear in the Drives panel

To remove scan information

1 Select an object on the R-Studio Drives panel
2 Select Remove Scan Information on the Drive or shortcut menu
> The scan information will disappear from the Drives panel


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