![]() ![]() The latter can be advantageous as it disables the look ahead buffer which may prevent lockups on a full track. ![]() In fact, they mean they can read from the front of the disk or the rear of the disk. It was not initially clear to me what they meant by read directions. The program itself can’t restore the images it makes. It’s not clear that the other format of pure sectors can be handled by other utilities, although I presume the actual Linux/UNIX DD command would have no problem with it. So they can produce a format which their non-free ($29) PhotoRescue can read to recover. dd extension, and a PhotoRescue specific format, created with the. Two formats are supported: one pure raw format, created with the. So the tool is more like dd which does fail on bad blocks than the other Linux tool “ddrescue” which does not. Their tool WILL lock up on a bad sector, which is why they provide for specifying start and end points. The impression I get is that this program is essentially a Windows version of the Linux/UNIX “dd” command. Still, if you are looking for an easy to use program to create a disk image for recovery purposes, you may find this one suitable for the task as long as you need to create an image of a non-system partition or drive. Several tools that we have reviewed in our data backup overview for Windows can do that including DriveImage XML. The program supports two read directions and it may make sense to create images using both directions to avoid situations where a drive image cannot be completed because of corrupt sectors.ĭataRescue DD is not the only program that enables you to create a disk image of a hard drive. This is a raw file that most recovery programs should have no troubles to read and process. dd extension will be saved to the local drive in the process. A click on the play icon starts the image creation and a file with the. ![]() You can specify the size in Megabyte as well as the start and end points for that, or the same for sectors of the drive. One interesting option is the ability to create a partial image instead of a full image. You should also make sure that you pick a destination that has sufficient free space to hold the data. Select the drive under source that you want to create an image of. If you run the software without the required rights, you will notice that no drives are identified by it. Vista and newer Windows users need to run the program with elevated rights so that the drive list can be populated. The program itself is relatively easy to use. It can not create an image of the system drive though, only secondary hard drives seem to be supported by it. While you can go ahead and try and copy all the data that is stored on the device to another, you sometimes may run into issues doing so especially if part of the drive is already corrupt or non-readable.ĭata recovery software may aid you in the recovery of the files in this case, and while you can run a program like Recuva, Free Recover or Unstoppable Copier to see if those files can be recovered, it is usually better to create an image of the disk first to run the recovery software on the image and not the original drive.ĭataRescue DD is a free program for Windows and Mac operating systems that can create an image of a hard drive connected to the system.
