    Additional areas on other disks can be selected in the Physical Disks list to be processed simultaneously. At least one selection must be made to begin disk image creation.

    Replace existing disk image files
    If this option is set, all chunk files will be replaced with a new once if their file names are the same.
    Ignore R\W Errors
    Ignore Read and Write errors during the disk image creation.

    Ignore Disk Lock Errors
    Any errors related to disk lock will be ignored;
    Compression
    Choose one of the following:
    • None [Raw Data] - No compression is applied, sectors are stored in raw format.
    • Fast - Sectors are compressed before storing to the file using a fast compression algorithm.
    • Medium - Sectors are compressed before storing to the file using a slow but more effective compression algorithm.
    • High - High level of compression;
    • Highest - Highest possible compression level ill be used;
    Store Disk Image in chunks
    Select this check box to save the Disk Image as a series of files with a specified size. Choose the file size from the drop-down list. This option may be useful if you want to write the Disk Image to CD-ROMs or DVD-ROMs. By default this check box is cleared and the Disk Image is stored in one large file;
  3. Click Create Image to initiate disk image creation process with selected parameters.

  4. Create image

    During the process:
    • To display or hide scanning events and progress details toggle More\Less Info button at any time.
    • To terminate the process, click Stop at any time. Results may be not accurate or complete.
    The file extension for a Disk Image configuration file is .DIM by default.
    The Destination Path for a Disk Image file must always be on another drive. File systems such as FAT16 and FAT32 do not support file sizes larger than 2GB and 4GB respectively. With these file systems it is not possible to create a Disk Image file for a drive as it is likely to grow larger than the size limit. The solution in this case is to do one of the following:
    • Use a Destination Path drive that is formatted using Windows NT, Windows 2000, Windows XP and using NTFS;
    • Create a Disk Image that is split into chunks of an appropriate size, keeping within the limits set by the file system;
    Use Create a Disk Image Wizard for the same purpose.
