New here so please bear with me!

I have an SD Card with some photos on it. It is formatted for an old Vodafone Android phone but the phone does not work any more so I need to access the card directly.

I cannot see how to mount an Android formatted SD Card directly in Linux such that I can see the photo files on the SD Card.

Would anyone be able to give me a step by step process to access the photos. I am relatively inexperienced with Linux but used to programme in Unix so am picking things up quickly.

I am running Ubuntu. I have an SD card slot that works fine with other SD cards.

Disks shows the SD card with:

  • Partition 1 (17MB): Device /dev/mmcblkop1
  • Partition Type 19a710a2-b3ca-11e4-b026-10604b889dcf
  • Contents Unknown

  • Partition 2 (8.0GB): Device /dev/mmcblkop2

  • Partition Type 193d1ea4-b3ca-11e4-b075-10604b889dcf
  • Contents Unknown

I ran sudo fdisk -l which shows:

Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes
256 heads, 63 sectors/track, 965 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes

I also ran sgdisk --print /dev/mmcblk0:

Further details from sudo lsblk -f /dev/mmcblk0:

NAME        FSTYPE LABEL           MOUNTPOINT                             

sudo blkid:

/dev/sda1: LABEL="System Reserved" UUID="46C204CAC204BFE3" TYPE="ntfs" 
/dev/sda2: UUID="EA66089566086523" TYPE="ntfs" 
/dev/sda3: LABEL="Data" UUID="06B6D646B6D635C1" TYPE="ntfs" 
/dev/sda5: UUID="cd798835-cf23-496a-a826-8603c60a3ecb" TYPE="ext4" 
/dev/sda6: UUID="de9c0c43-0775-421c-9b9c-4063fdf6a236" TYPE="swap"

/dev/sdc1: UUID="040D813E3C84050B" TYPE="ntfs"

I think that the android phone must have encrypted the card, hence why nothing is visible and as a result it will be impossible to retrieve any of the photos. If anyone believes there is a way to recover them then please let me know.

QUESTION: how to mount a GPT system?

  • The computer your using should have a slot for the type of SD card your trying to mount else it won't be able to mount it. And note linux does this automatically just put it in the right slot on your pc and it will pop up. – George Udosen Dec 11 '16 at 13:14
  • Are you running Ubuntu? Have you got a card reader? Did you try to read the card simply by connecting and trying with Ubuntu's file browser? If it does not work 'out of the box', you can try to identify the partitions and mount them manually with command lines in a terminal window. Please describe with more details 'what you have and where you are now'! – sudodus Dec 11 '16 at 13:17

    you can use back-ticks for code formatting (`) but you're off better to include your findings by doing an edit to your question. – Videonauth Dec 11 '16 at 18:16
  • What's the output of sudo lsblk -f with the SD card plugged in? – David Foerster Feb 23 '17 at 16:45

    Here is some useful information for recovery android_expand data: nelenkov.blogspot.ru/2015/06/… There said, that data at SD-card is encrypted and to read it you ought to have a key, which is stored at device memory. As your device does not work, it seems you can't read your photos. – Kirill Pavlov Oct 3 '17 at 15:27

    Just to clarify, the meta partition contains the encryption key, which is itself encrypted by your phone unlock, and that key is used to encrypt the expand partition. Once decrypted (requires the phone that owns the partition to be rooted), you get a plain EXT4 partition that you can do whatever with. – DustWolf Sep 13 '18 at 17:16

This post is quite old, so it probably does not help you anymore. Anyway, the filesystem used by your SD card is probably extended FAT, which, I think, is not supported by default. Installing support for this filesystem should be sufficient:

sudo apt-get install exfat-fuse
