Create a Disk Image

Using Active@ UNDELETE you can create a Disk Image of a Logical Drive or a Physical Device.

To Create a Disk Image:

  1. In Recovery Explorer, select a Logical Drive, a Partition or a Physical Device node.
  2. To open the Create Disk Image dialog box, do one of the following:
    • From the Tools menu, choose Disk Image > Create.
    • From the Recovery Explorer toolbar, click Create Disk Image.
    • Right-click the selected item and click Create Disk Image from the context menu.
  3. In the Create Disk Image dialog box, do the following:
    • To change the selected disk, choose one from the Disk drop-down list.
    • To specify an area to image, click Select. The Select Disk Area dialog box appears. Indicate the first and last sectors and click OK.
    • Enter the path to the destination folder in Destination path. To browse to the path, click the ellipsis button (…). If the disk image is saved in chunks, all chunk files will be created in the same folder.
    • Enter a brief description about this disk image for future reference.
    • To split the disk image into files of a specific size, select the Store Disk Image as chunks of size check box and select the size from the drop-down list.
    • To lock the selected disk and prevent any read or write activity during the disk image, select the Use Disk Lock check box.
    • Indicate the disk compression level. To make the disk image compatible with any third party applications, choose None [Raw Data].
  4. Click Create. The Processing... dialog box appears.
  5. To display disk image events and progress details, click Details.
  6. To terminate the disk image process, click Stop at any time. Results may be not accurate or complete. The disk image will likely be unreadable, if you stop.

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
