@manuel I know that already Both Etcher and WoeUSB have the requirement to unmount the drive, but that is not the problem. I just bought a new MMC card and tried WoeUSB again, but it failed and I tried every documented solution. Now I am running Etcher and making a Linux Mint installer as we speak…Flashing… one minute please… Validating… Success, or at least so far.
So although it seems that there is something wrong with the MMC cards, I still have a hard time believing they are bad, because “Card 1” one is not old and hardly used, and the other “Card 2” has only been used once to install Antergos, and I bought it because I had similar problems in the past: after Installing Antergos once with “Card 1”, The installer did not work anymore, Etcher wouldn’t burn the installer to it, and I had to use gparted to fix it, and that only worked in steps because gparted could not read the card after each step so I had to: Delete partition, close and restart gparted, create partition table, close and restart gparted, create new partition. After that I could burn the Antergos installer to it, Install it on another PC, and just for kicks tried booting from the card, and it was busted again.
I have installed Antergos for various reasons like 5 times, in the last few years, and always had to do it that way, and this time nothing works!
Anyhow fdisk reports this:
Disk /dev/sdg: 7.4 GiB, 7948206080 bytes, 15523840 sectors

Not having a disk identifier is odd, but I can still read and navigate the card in dolphin. XXXXXX
Well, before I wrote this reply, I was away for a few hours with the PC running, then I started writing up to XXXXXX, Installed an update (upgraded dconf-editor 3.30.0-1 -> 3.30.2-1) after which I just tried gparted again to copy and save the error, and it worked all of a suddon, and with both cards 1 & 2!!! What the??? The only difference I noticed is that the partitions (only one each) showed up as unallocated, even though I just navigated them in dolphin, not 10 minutes ago!
ARRRRRGH!!! This makes no sense at all, but I do have other strange things happening, mainly with KDE Plasma acting all crazy sometimes!
I would love to still figure this out, do you think if I run the Antergos Log file script, and attach the files to a reply (if I have enough privilege) it may show what the wierdness is going on?
I would think my computer is possessed, but I don’t believe in the supernatural!
