TestDisk | Recover SD card | Cant find any partition | Partition sector doesn't have the endmark 0xAA55

#1 Post by blaskowitz » 01 Jan 2017, 22:26

Hello and Happy new year to everyone!

Sadly today I found that my 32GB SD card that I use for my android phone can't be accessed and when I try to access it with Windows it gives the error "The volume does not contain a recognized file system".

I was able to successfully recover my files with PhotoRec and I'm really happy about that. However, there is the problem with losing the names of the files and all the meta info with it, and I really hope that I could recover my partition with TestDisk.

When I tried using TestDisk (followed the step-by-step guide - selected the drive-> selected intel partition -> then analyse) it resulted in the message "Partition sector doesn't have the endmark 0xAA55". Then when I tried Quick and deep search no partitions showed.

Here is the log from TestDisk after performing all those operations:

Is there any hope that I will be able to recover my partition?
I found some suggestions about selecting the "none" as partition, instead of "intel", but I wanted to ask for advise here first before doing something I'm not sure of.

Thanks in advance.

Try latest PhotoRec 7.1-WIP on this card. Do you recover your files/some of them ?

Yes I did tried using PhotoRec and it recovered most of my files, tried again with PhotoRec 7.1-WIP and although the recovery process was way faster, the names of the files still aren't the original ones.

I'm attaching a screenshot from Photorec 7.1

Will it be possible to recover my partition and not have to format the card or at least get my files actual names back?

I have the same problem of 0xAA55. No partition found by using intel

When use 'none' it shows unknown partition.

In Fat32 boot sector recovery it shows
Boot sector - bad
Backup Boot sector - bad

What to do with my sdcard is it repairable?

jagdish1221, did you try Deeper Search after Quick Search ? If no partition has been found, use PhotoRec 7.1-WIP to recover your files.
Once it's done and if you think all your files have been recovered, reformat your memory card.
