Ok, I had quite a rough time trying to make an ext2 partition in order to make an Ubuntu install on this card. At first I tried to format the second partition as ext4, but it never worked. after learning more about filesystems I decided to keep on trying it with ext2 instead as it would be more suitable for the flash Nand memory lifespan. Now analyzing my device, it seems that I have messed up it's partition table as it follows:

[  226.852201]  mmcblk0:
[  238.444150] Alternate GPT is invalid, using primary GPT.
[  238.444161]  mmcblk0:
[  247.014559] Alternate GPT is invalid, using primary GPT.
[  247.014567]  mmcblk0:
[  263.890523] Alternate GPT is invalid, using primary GPT.
[  263.890533]  mmcblk0:
[  266.468388] Alternate GPT is invalid, using primary GPT.

[ 5049.501468]  mmcblk0: p1
[ 5359.979893] rtsx_pci_sdmmc rtsx_pci_sdmmc.0: error -110 requesting status

Things I'd like:

  • Restore my micro sd card partition table
  • check it's health and try to restore any damage
  • get know once and for all why is it impossible to create a different file system in any new partition and...
  • Why Ubuntu refuses to be installed or use it as a partition of any kind saying that it belongs to user 999 as it were an audio device or something like that, does it have to do with the fact that it is owned by the RealTek card reader driver? Or is it related to the Sandisk secure vault?

Gparted partition error showing reported issue

I thought that installing or at least making subsequential logical partitions in order to increase Linux storage on SD would be easy piece, but turns out it is impossible or a real nightmare.
