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!

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

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

If a remote computer is connected for Data Recovery over Network, the Save Scan Information File dialog box will appear when you select a place to store scan info. You may save it to the local or remote computer.

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.

4R-Studio starts scanning the object, and its panel will show information about new found objects:

Click to expand/collapse R-Studio Main panel

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.

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 Recognized3.

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.

All scanned information may be deleted on the contextual 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 contextual 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. Control-click a necessary area and select either Merge Down, Merge Down All, and Merge Selected.
