Choosing Image File Format for Data Recovery

Post by viking » Tue Apr 28, 2015 3:59 pm

I have a failing hard drive and would like to create an image file that I can use to recover the data from. However, I would like to be able to use this image file with several data recovery programs, including R-studio, Active@ Undelete, GetDataBack, UFS Explorer etc. I believe that the best type of image would be a raw data (binary) image of the whole drive ("raw disk image")?

Thus, I need to find a third party application that can create such an image and can be read by various data recovery programs. However, I am confused about the different formats for disk images (are there different formats for raw disk images??). For example:
R-Studio can read image files with file extensions: rdr, dsk, dat, bin, dfs, fss, hex and arc
Active@ Undelete can read the following image files types: Raw Data (Binary), LSoft, Virtual PC, Virtual Machine (VMWare)
GetDataBack can read image files with file extensions: img, imc, vim
UFS Explorer ???

Which of R-Studio's extension(s) refer to raw disk image files? I assume that R-studio can not create raw disk image files (only a proprietary disk image format)? Any suggestions of a third party application that can create raw disk image files to be used with R-studio (and the other data recovery programs?

R-Studio can create raw (uncompressed) disk images. Just select the Byte to byte image option. See R-Studio's help for details: Images.
The file extension doesn't matter, you may select whatever you like, and change it if necessary. Raw file images are just data from disks, no additional information.

A related question - I created a set of .rdr images in an attempt to recover files from my RAID using R-Studio, but I would like to try to see if ReclaiMe's RAID detection algorithms can find the correct parameters for my volume. Unfortunately, ReclaiMe does not support the .rdr compressed images format.

But I do see that if I right-click on the drive within the R-Studio interface I can choose "create Image...", and from there I can create an image in .dsk format. Is this a byte-for-byte raw format that might be supported in ReclaiMe, and if so would this be a procedure for effectively converting or repackaging the data from within a .rdr file into an uncompressed disk image in a format that works with ReclaiMe and other applications?

Yes, this is a byte-for-byte raw format. I believe that ReclaiMe will support it, but I'm not sure.

If it's byte by byte then yes.
