Re: Micro SD card problem, cannot fix errors.

It could be a batch issue I suppose.
I now have 3 still with files, all files added between 2014 an 2020, differing on each of them. All with a different amount of fill and usage.
Somehow on two of them I now have no partition table, and gparted gives an error message when trying to create one.

I am still curious to know why they have failed. None of them have the "usbc" string scattered in the partition table, so it is not that, some Linux users have had failure upon either suspend or resume from suspend, but most of those saw the usbc string.

Re: Micro SD card problem, cannot fix errors.

[1257191.630039] mmc0: new high speed SDHC card at address 59b4
[1257191.630340] mmcblk0: mmc0:59b4 00000 7.35 GiB 
[1257191.649111]  mmcblk0: p1
[1257192.028782] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

So the card is actually assigned to /dev/mmcblk0 then? I presumed it was in a card reader or something.

Did you try using dd and/or wipefs on /dev/mmcblk0? Use dmesg to confirm the block device after inserting the card and before attempting to wipe it.

Re: Micro SD card problem, cannot fix errors.

I tried wipefs, dd, gparted etc.
I have to admit to still need to work my way through any dmesg entries.

I tried 3 different USB readers as well as discovering that the built in card reader works just fine under Linux. I was hard pressed to keep it working for more than a few hours under windows, so had forgotten it was there!

Yes dmesg does seem to show it is functional upon insertion and reading.
I am now trying to reliably run a fsck on it under linux, I do not seem to have all the tools that are suggested on the web.
