Images

An image is an exact, byte by byte, copy of any object on the Drives panel . When created, images can be processed like their original objects.

Images are very useful if there is a risk of total data loss due to hardware malfunction. If bad blocks are constantly appearing on a hard drive, you must immediately create an image of this drive.

While creating images, R-Linux can simultaneously perform disk scan and save scan information to lessen time necessary to process the disk.

All data search, scan and restoring can be done from this image.

To create an image ,

1	Select an object on the R-Linux 's Drives panel and click the Create Image button

Other ways to create the image

2	Specify image options, a file name, and destination for the image on the Create Image dialog box

Note: To store an image file, you need a free space equal to at least the object size.

Create Image dialog box

Image Options

Image name	Specifies the name and path for the image file
Plain image	If this option is selected, R-Linux will create a simple exact copy of the object. This image format is compatible with the previous versions of R-Linux .
Compressed image (R-Drive Image compatible)	If this option is selected, R-Linux will create an image file which can be compressed, split into several parts, and password-protected. This image file is fully compatible with the images created by R-Drive Image , but incompatible with the previous versions of R-Linux .
Image compression ratio	You may compress the data in the image to save space. Active only if the Compressed image (R-Drive Image compatible) is selected.
Estimated size	Shows the estimated size of the image file. An actual image size depends on how much empty space is on the selected partition and what file types are there . Active only if the Compressed image (R-Drive Image compatible) is selected.
Image split size	You may set this option to Automatic and let the system decide how to split the image file. This mostly depends on the file system on the destination disk. You may also either explicitly specify the split size, or choose a preset for various devices with removable storage. Select Fixed size for that. Active only if the Compressed image (R-Drive Image compatible) is selected.
Password	You may protect your image file with a password. Note: This feature provides a relatively moderate protection against conventional unauthorized access. Active only if the Compressed image (R-Drive Image compatible) is selected.
Create scan information file	If this option is selected, R-Linux will perform disk scan simultaneously with image creation. See the Disk Scan help page to learn scan options
Read retires	Specifies a value for I/O Tries , or how many times R-Linux will try to read a bad sector. R-Linux treats bad sectors in the following way: It reads a certain part of disk (predefined by Windows) and • If Default read attempts is set to 0, the entire part with bad sectors will be filled with the specified pattern. • If Default read attempts is set to a non-zero value, R-Linux reads again that part sector by sector, repeating the attempts the specified number of times. If R-Linux still cannot read a bad sector, it fills the sectors with the specified pattern. In this case only the bad sectors will be filled with the pattern, but that extremely slows the disk read process. For example, if you set Default read attempts to 1, a bad sector will be read 2 times.
Pattern to fill bad blocks	Specifies a pattern R-Linux will use to fill bad sectors in this image. You may specify the pattern either in the ANSI or Hex data format. Note: R-Linux will never ever try to write anything on the disk from which data is to recover or an image is to create. This pattern fills bad sectors only in the image.

>	R-Linux will start creating the image, the Progress message showing the progress.

You may change some options during the imaging process. Click the Options button and change them as necessary.

You may stop the imaging process and then resume it later on. Click the Stop button and the Cancel drive operation dialog box will appear. Select Stop if yo want to keep the partially created image or Discard if you don't need this image file.

To resume the creation of the image for the same object, select the same file name for the image. You'll be able to create a new image file or continue to create the image for the object.

Resuming image creation

R‑Studio for Linux will create a new file for every new start of imaging for the .rdi file type.

To process an already created Image , the image file should be opened.

To open an image

1	Click the Open Image button , or

Select Open Image File on the Drive menu

2	Select the required image file

>	An Image object will appear on the Drives panel

Depending whether this is a byte-by-byte , compressed ( R-Drive Image compatible), or multi-volume , image, its appearance in the Drives panels is different.

You may perform all data search, scan, and recovery from this image as it were a regular drive/disk object.

To close an image

*	Select the image and click the Close Image button,

• or right-click the image and select Close Image on the shortcut menu

• or select the image and press the F8 key.

To close all image

*	Select Close All Images on the Tools menu

A logical disk (or disks) containing in an image can be mounted in the operating system as a device which makes its content accessible to any program including any other data recovery software.
