Hi!

I was doing a transfer from pc to sd when the system crashed. after restarting windows asks to do the scandisk on sd . once again the system hangs completely and the only solution after hours of waiting is to restart the computer. here the problems begin. about 10 GB of data in sd are gone (though the space occupied is still the same as when they were available) and appear a folder "found.000"
inside the folder there are files much file chk with 32kb size and 3 files about 300mb which are the ones that I was moving when the system crashed.
I tried it on another system to re-run the scandisk to reassemble the file system but at the end of the procedure the message that the file system is no longer recoverable.
is it possible to somehow recover about 10 gb of files in the sd?

thanks to all

Maybe, but it is a tedious and time-consuming process without guaranteed success. And there will not be a logical directory structure as before.

If the data is not important, then it is not worth the time.

thanks,
if i want to try to recovery what program that you suggest we use?

thanks

There is no automated solution that I know of. If there was, it would NOT be tedious and time-consuming.

Have to do work on it manually, buy looking at file headers in hex and try to change/rename each file to its appropriate file extension. Then, you check the file to see if it works as it should.

Recommend that you make a copy of the damaged files and work off/alter the copies.

*Of course, all of this above given that I do NOT misunderstand/misinterpret your situation. Keep in mind that this a remote suggestion on the forum, so the risk of further damage is all on you.

I saw someone mention this the other day:

http://trcdatarecovery.com/articles/chkdsk

"TRC Data Recovery have released a new software application called ChkBack which is designed to retrieve data that has been lost after ChkDsk has scanned a drive and relocated file fragments"

I have never used it myself. If you do try it, make sure you make a full image (and backup of the image) of the SD card first and try it on the image.

Yes I mentioned that link samsung-hdd-changed-raw-t24820.html?hilit=trc

"TRC do a software that will tell you what extention the .chk is http://trcdatarecovery.com/articles/chkdsk then you can rename the .chk to say .jpg as an example but you wont have file names or folder structure. Its going to be a lot of hard work renaming the extenstions unless you can organise them in folders ie jpg, doc, docx etc then you could rename them possibly in a batch using cmd"

You could also use X-ways (Winhex Forensic Version) then check signature then export the file with the correct extension !
So it can be a very quick process !
