Need help to recover a 128GB microSDXC

#1 Post by robinthebest »

Tried using both photorec and testdisk to recover files, both unable to recover anyfiles.

Unable to rebuild boot sector, am i doing something wrong?

If i wanted to start from the get go, which log should i post first?

TestDisk generates a log file named testdisk.log, please copy and paste its content.
Is PhotoRec/TestDisk reporting the correct disk capacity ? If it's not the case, you should contact a data recovery company as the flash controller or the memory chip is probably damaged.

Even "thebest" might consider providing an error description. :idea:
Look what others users wrote and you will quickly get an idea what is useful or not.

Another good start is the manual:

https://www.cgsecurity.org/testdisk.pdf

Cross-read the documentation

https://www.cgsecurity.org/wiki/TestDisk

to find information that applies to you.

I'm sorry I didnt have the time to do a follow up before and i just did it today,

below are what i found from log, i did a quick search and deeper search and couldn't found anything, I also tried photorec but it didnt find any files either, Windows is telling I had to format the disk before using it

I would either use a hex editor to look the drive's sectors just to see if that produces read errors or not.
If you duplicate the drive with ddrescue you can check the logfile during and after recovery to see where a sector is not accessible.

You did not say what you expected to see on your drive.

I will try to duplicate the drive with DDR, but i don't get the hex editor part, how do I do it?

I had a lot of photos in this SD card, so basically i wanted to recover them, at least recover some of it

Has your drive been encrypted?
You open the drive with a hex editor like HxD p.e.. You scroll through the sectors awaiting a "read error" message box.
Simultaneously you look at the content. Maybe you only see zeros.

No, it has not been encrypted.

And strangely, after i had right click on the drive in explorer with open as portable device, i can click into the drive again, although after I click into the folder the explorer completely froze, so what should i do in this case? should i just use photorec or i should try repairing it by using testdisk first?
