Is it possible to recover RMVB, ISO and NRG filetype?

Post by haresh » Wed Oct 20, 2010 4:41 am

Hi everyone,

I have a 500 GB hard-disk, formatted by mistake :cry:
I tried some other software and could recover the data, but missing few very important file-types i.e rmvb ( Video), iso ( Disk image) and nrg (Nero Disk image).

can someone help me getting .xml file written for these data types?

Thanks for your time and help.


PS: In options we can select or deselect the file type to be recovered, but there are few file types which we can not deselect, is there any way to do that, so i can only search for rmvb, iso and nrg types.

The known file type file for the ISO images is
<?xml version="1.0" encoding="utf-8"?>
<!-- Search for iso files -->
<FileType id="5626" group="CD/DVD Images" description="iso files">
<Signature offset="32769" count="1" size="5" from="begin">CD001</Signature>
I need samples (small) for the rest of files.
There are several reasons why some file types cannot be unselected, but the most important thing is this:
R-Studio detects the end of a file when it meets a file signature of another file type. That results in the following:
1. Only unfragmented files can be recovered this way.
2. Although the less number of selected known file types, the faster the scan is, it's recommended that only those file types should be unselected that surely are not present on the disk. This rule greatly enhance detection of the file end.
