Question How is microSD error 123 felt like?


As for gdisk is gone against opening the card, which progs could be helpful to deal with the error ‘‘123’’?
Code:
[hd_scania@hd-scania ~]$ sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 1.0.3
Problem opening /dev/sdb for reading! Error is 123.
[hd_scania@hd-scania ~]$ sudo cgdisk /dev/sdb
Could not load partitions from '/dev/sdb'! Aborting!
[hd_scania@hd-scania ~]$

if you could not open that card for reading nobody can help you. You can simply try cat /dev/sdb > /dev/null to check if that card is readable.
Also you can check /var/log for a better error message.

A possible solution (to reuse the card) - clear the first few MB,
Code:
sudo dd if=/dev/zero of=/dev/sdb bs=4M
then give it a new MBR, re partition, & put a file system on it.

that dd was not successful. It could not write anything onto /dev/da0.
Did you try the cat command I posted?

As given before, my cat result was Device not configured, and it gets perplexed how and why it reports not configured.
Given here, the card is NOT visible to sudo gpart.

ok, sorry, did not see that. So this card is not usable. Either the reader or the card itself is not ok (or both).
You can try another card, another reader (or probably another OS).

The same card with THREE readers was usually NOT visible to any disk managers, or seen outside but NOT readable inside
Now i still have an emptied card working fine, but 2x smaller than the dead one.

Looking like it is dead/corrupted - I've come across other people with dead micro SD cards, they don't seem to be too reliable.

One of the reasons that I don't want to rely on them on my RPi computers, I prefer to USB boot them.

Dead/corrupted ... You mean the card was hard-bricked?
If not, how to recover those data for myself?

And the microSD was dead on an Android, but NOT a desktop, and iíve put it onto a HBSD/Linux desktop as for data recovery.

there is no way to recover anything if you get only errors when you try to read it.
you might try testdisk to recover some data.
