Hi Were you able to create the file ALT ?

No, because there's no end signature for mts files.

The problem is that, because MTS files don't have a common pattern for their end, R-Studio finds the end of such file just before the beginning of a new one. So, quite often a lot of garbage is included into found files. That garbage has to be removed manually in a Hex editor. You may use the R-Studio's for that.
Also, such files may overlap, that's quite often their total size may well exceed the size of the host disk.

Hi Alt,

With this I can find the MTS files but they are way bigger then the original size.. the original files have between 10Mb to 300Mb.. the files I found don´t have less then 1Gb / 2Gb..
When I recover one of this files it is working..
This drive is a 750Gb Toshiba and I can find more then 10Tb of MTS files.

Any ideas? Why the files don´t have the original size?

Thanks

<?xml version="1.0" encoding="utf-8"?>
<FileTypeList>
  <FileType id="5318" group="HD Video Camcoders" description="MTS Video Files" extension="mts">
    <Signature from="begin" offset="4">G@\x00\x10\x00\x00\xB0\x11\x00\x00\xC1\x00</Signature>
  </FileType>
</FileTypeList>

As I understand, this should work for all MTS video files:
[code]<?xml version="1.0" encoding="utf-8"?>
<FileTypeList>
<FileType id="5318" group="HD Video Camcoders" description="MTS Video Files" extension="mts">
<Signature from="begin" offset="4">G@\x00\x10\x00\x00\xB0\x11\x00\x00\xC1\x00</Signature>
</FileType>
</FileTypeList>[/code]

Hello, yeah sure..

There are 3 small files from this camera. Let me know if you need something else.

Thanks

It'd much better to have such files on hand, rather than the screenshots. 3-4 movies of 1 sec would be more than enough.

Hello guys,

I have a SONY HDR-SR12E. Recently for mistake I quick format my external drive with all the files created by this camera on it. Making a scan I can find part of the structure folders with a lot of mts files but there are missing a big part of them.
I was reading this post about this kind of files and I noticed the same issues because r-studio can´t find any files besides the ones with folder structure.
I tried to add all the new codes in this post but no file was found.

I open 4 mts files in wex mode to see the signatures and this is what I found:

This is the beginning of the files, highlight are the differences..

This is the end of the files..

Can you guys help me to create the code to be able to find the lost files?
Let me know if you need something else.

Thanks in advance

I think your files on the card are fragmented, that's why they appear damaged. Actually, it may be possible to recover the files, but I can't say more definitely without seeing the data, and such task is for a data recovery professional only.

[quote="Alt"]were those files recovered from the restored file system on the card (using their original names) or just using scan for known file types (from the folder Extra Found Files), and if the latter, did you use the file type description from this topic?[/quote]
1. Have tryed to restore file system from the drive(turned read-only before to prevent further damage).
2.Then have tryed to scan for known file types with the signature from this topic, have found 32 GByte of data(card has size of 16gb only but the cam itself writes temporary files, and then deletes them by itself, but in the restored file system were those temporary files as well). However all files which are restored are damaged, no sound, imageproblems and such.

Question: Is there a possibility to find a file with whole Info? There are extra XML files with description of those mp4 containers, maybe its possible to make the search more precisly with it? Have made data-image from the card with r-studio and working only with it.

[quote="a_und_r"][quote="Alt"]Was it a full format or a quick format?[/quote]
I thought it was formatted with quick format under w7, but the one who made it just told me he made this format in the cam itself. Probably also some type of quick format.[/quote]
And another question: were those files recovered from the restored file system on the card (using their original names) or just using scan for known file types (from the folder Extra Found Files), and if the latter, did you use the file type description from this topic?
Sorry for a lot of questions, but I have understand what you did.
