Can you copy and paste the content of your testdisk.log into your next post using the expert mode?
You'll find your testdisk.log within your testdisk folder.
Open it using a wordprocessor like wordpad and copy and paste the content.
Please add a screen shot of your current partition table also.
It's TestDisk / Analyse and current partition structur (it's your current partition table).
When you tried to list and copy files, did you get any message?
Did your selected files appear green colored?
TestDisk 7 final is already released, please use the final release and the 32bit version.

You can zip it!
Normally there is no necessity to run None, unless testdisk suggests it automatically.
Running None, there will be no partition table available.
Only boot sector repair and if files ar listed, to copy them.

TestDisk didn't find any partition using partition table type Intel?
Your partition table is empty!
Using partition table type None and running the menu Advanced doesn't help as much either.
Because your flashdrive is only recognized as an unknown drive and adding a file system using type like Fat32 LBA may not use the correct values of your previous lost partition!
You can run another diagnose running partition table type None and Analyse, Quick and if nothing is found Deeper Search also.
Partition table type None scans in comparison to Intel more sectors and can find more partitions.
If any partition would be found and you're able to list your files, you can have try to copy them to another healthy disk and partition.

now I did use photorec.
photorec finds also files, which I can´t open and I don´t know, what these files are do.
- AI-File (name.ai)
-ELF-File (name.elf)
-H-file (name.h)
-m-box file (name.mbox)
-xmb-file (name.xmb)

and why can find photorec more files as testdisk?
(it finds also xls, word, ppt, pdf and so on)

PhotoRec ignores the file system and reads underlying data.
PhotoRec can help if your file system is seriously damaged.
TestDisk is a partition recovery program, it can list files and even undelete files.
If TestDisk lists files you can copy them to another intact disk, partition and folder.
TestDisk keeps file names and directories.
photorec finds also files, which I can´t open and I don´t know, what these files are do.
To achieve better results, you can use PhotoRec / FileOpt and press s to deselect all file types.
You can mark only these file types where you'd like to recover.
So it doesn't recover any unnecessary files.

Hi Fiona,

thanks for your help.

Ok I delete now all files, which I don´t need.
Can I now "normaly" format my USB-Stick (with windows-programm) or should mind anythink?
