Questions[micro-sd](ubuntu)

I know that there was many similar topics but I haven't find answer yet. On my Ubuntu, sd cards are everytime read only, I can't write on it or format. I can do everything on other devices (Android, Windows). When I try to format it on gparted, I get following error:

error checking file system on /dev/mmcblk0p1: error when trying to detect filesystem on'/dev/mmcblk0p1': Failed to open device '/dev/mmcblk0p1' (udisks-error-quark, 0)

I tried 'sudo hdparm -r0 /dev/mmcblk0' but without succes. Any ideas?

EDIT: I can make this:

sudo hdparm -r0 /dev/mmcblk0p1
sudo mount -o remount,rw /dev/mmcblk1 /media/adrian/1C14-3325/

Then I can write and delete on disk, but I have to repeat this everytime I unmount card and still no possibility to format or use dd command.

When I turn on my computer, it goes into the Ubuntu interface and asks me what I want to boot into:

Ubuntu
Advanced system options for ubuntu 
Windows boot manager (on /dev/sda1)
System setup

When I boot into the “Ubuntu” option, it just shows a command prompt that runs a few commands:

[   3.075355] sd 4:0:0:0 [sdb] No Caching Mode page found 

[   3.075388] sd 4:0:0:0 [sbd] Assuming Drive cache: write through

This is my only computer and I don’t know much about Linux.

Thanks for your time!

I bought MicroSD SanDisk PRO V30 A2 128 GB to which I would like to install Ubuntu 18.04 (is it possible to install linux on it?)

Currently I have Ubuntu 18.04 on a USB (SanDisk 32GB). I also have Windows 10 on the eMMC drive (only 32GB)

So now, Ubuntu doesn't read the new microSD. I tried on Windows 10 and reads it and found out there is only two options to be formated to: NTFS and exFAT.

What should I do to make this MicroSD be compatible with Ubuntu so I can install it.

I have a 64GB micro sdcard which was removed from an android phone without unmounting (could not find unmount after upgrade to android 7.1,they tried to make it easy and intuitive - it is an eject icon, 6 levels deep in the menu, so cannot be found by search for "unmount")

now the sdcard can be mounted and unmounted, data can be copied from it, but writing to it, deleting files or formatting it or writing new partition table is no longer possible; deleting files appears to work, but after unmount and mount again, everything is back to the way it was when it first started erroring out while copying files to the micro sdcard from linux; so writing to the card worked for a few mount/unmount cycles after taking the card out of the android phone without unmount;

trying to format it in the android phone errors out; in a camera, it says memory card locked; in ubuntu 18.04:

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=512 seek=1

stopped it by control-c after 4GB, still no changes, files are still there, cannot write to micro sdcard

Basically, it seems that formatting, gparted writing a new partition table, fsck clearing the dirty bit, even writing with dd, all have no effect. The micro sdcard is not physically damaged, mount/unmounts just fine, which is why I thought that formatting it, and if not, then using gparted to write a new partition table should totally clear it and make it like new again. What am I missing? Why can't I format it? Is there something else I can try? It is as if it has some settings in there which cannot be accessed by these tools; it is a transcend micro sdcard

edit: tried to format the micro sdcard on windows xp, it said the card is read-only; connected with a usb micro sdcard adapter which showed the card as 32GB, and then with a multicard reader (micro sdcard into sdcard adapter into reader, usb out of reader) which showed 60GB and read-only; the problem is not the adapter, as I inserted the card in a laptop with ubuntu 18.04 that has a micro sdcard slot, so no adapter, and also in an android phone, again, no adapter;

tried mkusb-dus, but it refuses to wipe or reset the card

tried dd to overwrite entire card, but after mounting it again, everything is still there; files can be copied but not deleted; cannot create partition table to reset sdcard

I read there is a read-only diskwide attribute I will try to see if I can reset that

I have a laptop that currently has no OS. And the DVD drive isn't working. I already managed to download the Ubuntu iso on my Samsung j3 phone. Question is: is there an app that operates like pendrive, allowing me to burn onto a microsd card? Something that doesn't require rooting and/or OTG?

Thank you,

Jeremy.
