Motorola g3 and unreadable SD Card

A couple of days ago the SD card (which is the "expanded filesystem" from android 6.0) on my phone stopped working. The phone still boots and works, but all my data (especially photos and WhatsApp conversations - yes, I didn't make a backup, shame on me) are gone. I removed the SD from the phone and put it in my PC, where Fedora recognizes the partitions but cannot mount them. Here's the output of fdisk -l: fdisk -l /dev/sdc Disk /dev/sdc: 29 GiB, 31104958464 bytes, 60751872 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 938FFB3B-CA49-45D0-89B3-BE22ADAAD86E Device Start End Sectors Size Type /dev/sdc1 2048 34815 32768 16M unknown /dev/sdc2 34816 60751838 60717023 29G unknown Whenever I try to mount one of those partitions, I get mount /dev/sdc1 /mnt/test mount: /mnt/test: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error. Same result if I use the -t option with auto, vfat or ntfs. If I open gparted and attempt the data rescue this is what it finds: and when I click the "View" button it correctly recreates the Android filesystem, but with no file inside: tree . ├── Android │   ├── data │   │   ├── com.android.vending │   │   │   └── files │   │   ├── com.google.android.apps.maps │   │   │   └── files │   │   ├── com.google.android.gms │   │   │   └── files │   │   ├── com.google.android.googlequicksearchbox │   │   │   └── files │   │   │   ├── download_cache │   │   │   └── pending_blobs │   │   ├── com.google.android.music │   │   │   ├── cache │   │   │   └── files │   │   ├── com.google.android.videos │   │   │   └── files │   │   │   └── Movies │   │   ├── com.google.android.youtube │   │   │   ├── cache │   │   │   └── files │   │   └── com.motorola.migrate │   │   └── files │   │   └── Pictures │   └── media │   ├── com.android.providers.media │   ├── com.google.android.talk │   └── com.motorola.MotGallery2 ├── bluetooth ├── DCIM │   └── Camera ├── Download ├── LOST.DIR ├── media │   └── audio │   └── notifications ├── Music ├── Ringtones ├── System Volume Information │   └── IndexerVolumeGuid └── WhatsApp └── Media ├── WhatsApp Audio ├── WhatsApp Images └── WhatsApp Video 44 directories, 1 file Has anyone any idea?
