Hello together A few days ago, I worked on my weekend-PC. I don´t know the rason, but on this day I thougt that the usb-ports are slowly (external HDD). After I restartes my PC the USB-Stick seems to be empty. But on the Stick is shown, that there are 2,55GB Files. Does anybody know, that has happend? please look at the both pictures: ( categories: )

Disk dead
Sorry, but it looks like your disk has died. While it still partly works, it's reporting the wrong things, and so the unit has probably died. You might wish to try checking for errors just to make sure (though it looks like you've done that by the fact that there's the FOUND.000 folder). In the disk properties window, there's a button in the "Tools" tab in English - maybe the "Extras" one in German?
It is extremely improbable that you can restore the files, especially if the disk is faulty.

HI :) I think the files are
HI
I think the files are lost, too. But I don´t think, that the disk is death. The one is, that the manufacturer gives me 30 years warranty on the stick. The other reason is, that the tool "hd-tune" don´t find any damaged sector. Unfortunately the tool shows 1605kb for one sector.
Do you know a tool, whis is able to scan each bit?
Well, I think, I beginn to formate the stick, and upload my last backup. (to surf with a DVD-Backup is pedantically)
try photorec tool
checkdisk seems to have renamed/changed your data..

no such tool
>Do you know a tool, whis is able to scan each bit?<
no such tool will do anything on a flash stick. Remember, the flash uses its own flash file system, the windows or what ever file system is only virtual on the top of that. It has no real address-bus and will definitely prevent to do any operations on its internal sectors unless it is allowed to clear the sector completely and this will be in general only if the sector is full. The flash is divided into sectors and zones and allocation where what is written to is done on some complex and mostly kind of secret and obscure calculations to ensure wear leveling.
You have probably single level flash (warranty many years) and so also the rest of the work done by the controller will be rather sophisticated.
Format the stick to something like fat32 and start from scratch. Software which we have all is based in general on file systems of DOS/WIN or linux etc, and will thus in maximum inspect bits of the virtual file system and virtual sectors and virtual what ever. If scanning sectors of some virtual structure will not bring you any further here. The check files the scandisk did produce are just estimations it did, since it did not find any complete record of file allocation table or similar important information.

.chk files
Aren't .chk files scandisk error files?
You did take a backup, right?
Trashed data?
Uh oh... One of the screenshots you posted shows as "Trashes" file - have you checked it with an antivirus program? It sounds like you've got some kind of virus which trashes data? ("THRASHES-Datai" - I assume this is your language for "Trashes data"?)
Mac
It's been used on a Mac, that's how they do trash on drives, USB included.
