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.

You may save scan information on the remote computer if necessary.

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 Scan dialog box will have a different look

and 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 .
