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 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 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 for Linux can recognize the data’s particular file type . Using such information, R‑Studio for Linux can obtain more information about data/file structure on the object being scanned. By default, R‑Studio for Linux 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 for Linux 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 for Linux Settings .

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

An existing logical disk or partition

An existing logical disk or partition after disk scan

A recognized partition. Both boot records and file entries are found for this partition

A recognized partition. Only file entries are found for this partition

A recognized partition. Only boot records are found for this partition

A fast found 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 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 Recognized1 on the Partition5: .

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.
