Data Recovery and Disk Utilities Forum @R-TT

File fragmentation mostly depends on how often data was being deleted, written, and overwritten on the disk. Also, if those VHDs were static or dynamic. Nothing can be said conclusively until the end of data recovery. And if it's successful, the recovered files weren't fragmented. Otherwise, a lot of causes may make data recovery fail. Starting from some bugs or imperfect data recovery algorithms of R-Studio to mistakes during the process of data recovery to fragmented files.

Thank you!
The deleted files are on external USB drive. Does it guarantee non-fragmented write? How do I know if the files are fragmented?

1. Download the latest version of R-Studio.
2. Use this file description file:
<?xml version="1.0" encoding="UTF-8"?>
<FileTypeList version="1.0">
<FileType id="113" group="Disk Images" description="Virtual PC Virtual HD Image" features="" extension="vhd">
<Signature from="begin" offset="512">\x63\x78\x73\x70\x61\x72\x73\x65\xFF\xFF\xFF\xFF\xFF\xFF\xFF\xFF</Signature>
<Signature from="end" offset="512">conectix\x00\x00\x00\x02\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00</Signature>
</FileType>
</FileTypeList>
3. Disable all other file types when scanning.
4. Pray that the files aren't fragmented.

And good luck for file recovery.

does the second sector (Sector 1) of all VHD files contain this string at the beginning:
63 78 73 70 61 72 73 65 - FF FF FF FF FF FF FF FF ?
or a part thereof?

Exactly! I analyzed all VHD files I have in HEX editor and the second sector (Sector 1) always starts with:

We're testing it.

When the release is expected?

I'm waiting for the next R-Studio version, it has some improvements in processing known file types. It's going to be released soon.

Have you played with recovery of the test VHD file?

I downloaded the files and will look at them soon.

Please try to place a sample Original.vhd on a HDD, delete it using Shift+Del and recover with the current vhd.xml .
