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

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

The image can be saved on the remote computer if it is created via network . R‑Studio can also load and process images created with the DeepSpar Disk Imager™ .

To create an image ,

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

Click to expand/collapse Other ways to create the image

• Select the object and select Create Image on the Drive menu

or

• Right-click the selected object and select Create Image File on the context menu

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.

Image name

Specifies the name and path for the image file

Byte to byte image

If this option is selected, R‑Studio for Linux will create a simple exact copy of the object. This image format is compatible with the previous versions of R‑Studio for Linux .

Compressed image (R-Drive Image compatible)

If this option is selected, R‑Studio for 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‑Studio for 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 OS 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‑Studio for Linux will perform disk scan simultaneously with image creation. See the Disk Scan help page to learn scan options.

Read attempts

Specifies a value for I/O Tries , or how many times R‑Studio for Linux will try to read a bad sector.

R‑Studio for 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‑Studio for Linux reads again that part sector by sector, repeating the attempts the specified number of times. If R‑Studio for 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‑Studio for 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‑Studio for 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.

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

> R‑Studio for Linux will start creating the image, the Progress message showing the progress.

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

If a remote computer is connected for Data Recovery over Network , the Open Image File dialog box will appear when you select a place to load the image file from. You may load it from the local or remote computer.

2 Select the required image file
> An Image object will appear on the Drives panel

Depending whether this is a byte-by-byte or compressed ( R-Drive Image compatible), 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.
