How to reconstruct a file from a JFS partition to save it on a NTFS partition?

Hello Experts!

My wife digitized an old VHS video using a pendrive plugged on a timemachine USB port from a TV LG47LE6200 and throwed the VHS tape in the trash can!

Days later, after know what ocurred, I told her: - No problem, I will plug this pendrive on my laptop to send the video file to our external hard drives.

Surprise: The laptop did not recognized the pendrive.

After some research I found that LG timemachine formats the pendrives using a obscure file system named JFS (journaling file system).

Tragedy: Then I changed the drive letter of the pendrive using "Paragon Partition Manager" and "Raise Data Recovery" trying to get the video, but only saw hundreds of files with strange names where should be the video file and the pendrive was turned unreadable by LG timemachine!

Despite this I think that the video data wasn't lost. Apparently, the video file data should be scattered through all those 251 files named 0000000100000001IDX, 0000000100000001STR, 0000000100000001THM, etc inside a folder named 00000001REC because the size of all those files appears equal to the same size of the original video file.

Then my question is:

How can I reconstruct the video file from all those files to save it on a NTFS HD?

Best regards!

Hi RX 180 Linux?
The Journaled File System (JFS) is a journaling file system that was open-sourced by IBM in 1999 and support for which has been available in the Linux kernel since 2002.
In the event that the file system does not get properly unmounted before being powered down, one will usually have to run fsck on a JFS file system in order to be able to remount it.
This procedure usually only takes a few seconds, unless the log has been damaged. If running fsck returns an unrecognized file system error, try running fsck.jfs on the target device.
Normally, fsck is all that is needed.
If the superblock on your file system gets destroyed, it may be possible to recover some parts of the file system. Currently, the only tool able to do this is a utility called jfsrec.
JFSrec is currently available from the AUR using the jfsrec-svn package.
There is also an AUR package called jfsrec, but this is merely a placeholder for jfsrec-svn as JFSrec is currently only in its seventh SVN revision. Once installed, one simply need to type:# jfsrec to get a help menu explaining how to use this utility.
Warning: As stated above, JFSrec is only in its seventh SVN revision; and it is not known how actively the project is maintained. So use JFSrec with caution.
Cautionary notes

How to use it

If you write to the drive the data that was there is gone and you cannot recover it.
Try the demo of  JFS Data-Partition Recovery Software

You didn't grab the VHS out of the trash?
What was the TV program.
Maybe hope to just find what you recorded?
There was a simpler way to digitise this VHS.

Hello Merete,

Sorry for the late reply.

Answering to your questions:

I could not get the VHS tape from the trash because I only realized what had happened a few days later. My wife does not like to keep "moldy junk" at home. :(

The tape contained family scenes from the 90s, so it would be impossible to find them on the Internet.  

On the same day I posted this question I found the tutorial below that allowed me to retrieve the video file.

I don't returned here before because the politics in my country is boiling.

Then I used the Raise Data Recovery program to transfer the *STR files to one HD and then I used the TS Doctor program to rebuild and convert the video file to the format *.ts.

It was very easy.

In any case I thank you for the effort to answer me.

This is the first question I ask here so I'm not sure how to proceed after now.

The tutorial I used:

Extracting the videos

Option 1: Connect the TV HDD on Linux (Live-CD, VM, HDD etc.)
Open the folder "00000001REC".
The videos are the files ending with the suffix "STR". It's you decision to copy all files or just the "STR" files. Depending of the amount of files, it is more worthwhile to copy all. You need root access to copy the files.
Option 2: Using Nucleus Kernel JFS on Windows
Select the "Storage Device" at left menu.
Check "Use Partition Table" option and click "Next" button (Sometimes NKJFS don't find the partitions, just reinstall NKJFS and try again).
Select "JFS - 0" at left menu and click "Next" button.
A window will open, check "Normal Search" option and click "Ok" button (wait about 5 seconds).
Select the folder "00000001REC" on the left menu.
The videos are the files ending with the suffix "STR". It's you decision to copy all files or just the "STR" files. Depending of the amount of files, it is more worthwhile to recover all.

Fixing the videos using TS Doctor

Open TS Doctor, go to "File" menu and open the "STR" file without change the extension.
Wait TS Doctor cheks the file, TS Doctor must find 2 tracks: H264 Video and AAC Audio English.
If TS Doctor detects more than one audio track (E-AC3 German for example), click on Tools icon of the invalid track and uncheck "Stream Enabled". If you wish, change the language of the correct AAC track.
Click "Save new File" button and choose a new name for the file.
A file with "fixed" sufix and "ts" extension will be created.

My solution was more economic because the software costs.
That's pretty good method RX 180
I've been thinking of pulling out the drive from my DVR set top box, I have discovered it has software onboard and I might try and replace the drive but need the software.
I am so happy for you that you were able to recover it.
May I add a technique with VLC, it has a record feature you can record the video playing and it will save it as an mp4 if set or mpeg. Just go to tools and tick to show advanced tools
See the red dot?
Go to preference set the directory to save the video, it names it date and time just rename it.
Thanks and all the best
