DataRescue's DD (in short DrDD) - is a graphical disk imager intended for data recovery and backup of partially corrupted storage devices. DrDD creates complete or partial images of disks or memory cards to files on another storage device, allowing multiple data recovery attempts on the raw data, thereby minimizing the risk of damaging the corrupted media further. DrDD is available for Windows PC and Mac OS X machines.drdd interfaceSource: this is the damaged storage device you want to recover from, in this case, as 750 GB NTFS drive.Destination: this is the file where data read off the media will be stored. Since DrDD can backup partial areas, the default naming scheme will include, as a reminder, range information. Two formats are supported: one pure raw format, created with the .dd extension, and a PhotoRescue specific format, created with the .cib extension.Range Selection: there are two ways to select the portion of the damaged media that DrDD will attempt to read: by size, or by allocation units (commonly referred to as sectors). In this case, we are attempting to read 175.000 MBs starting at 100.000 MBs and ending at 275.000 MBs. The default selection is to backup the whole device. Coarse interval selection is achieved through the MBs interval boxes. Fine grained interval selection is achived through the Sectors interval boxes. This feature would typically be used with a hard drive that suffers from bad sectors or a memory card that locks up because if a defective memory bank.Read Direction: the creation of the copy can be done by reading the device forward or backward. The default copy direction is forward. Copying backward may be interesting because, in some cases - typically hard drives - it disables the look ahead buffer and therefore reduces the risk of lock up on a full track.Log Window: will display messages about the program's operation.Last Log: this button will call up the last log. Since a hardware crash may completely lock a system, it may be difficult to determine exactly where the damaged area begins. If a lock up occurs, the system should be reset, and the log viewed to determine the last safe sector to read.
