how to recover damaged memory card with the help of Ubuntu?

Question

I have 16 gb micro memory card but it suddenly damage and unable to read and open. it only display in Disks utility. also when I insert that memory card into mobile it display message Damage memory card format it. but if I format memory card I loss all my data. How can solve that issue. Here is screenshot of Disks Utility.

Solution

If there is a Microsoft file system, FAT32 or NTFS, try to repair the file system in Windows with

chkdsk /f X:

where X: is the 'drive' letter, for example D: or use a graphical tool in Windows. (You already know that you should not format it.)

If there is a linux file system, try to repair the file system in linux. Ubuntu uses the ext4 file system, which can be repaired with

sudo e2fsck -f /dev/sdxn

where x is the drive letter and n is the partition number, so for example /dev/sdb1

---

If no luck try Testdisk.

If still no luck try PhotoRec, which can recover files without a file system. The drive must be seen as a mass storage device, and Disks sees it as /dev/sdb, which indicates, that this is the case.

It seems your drive is toast. Can you make an image of it using the Disks application?
