[RPi5] Error in mount_flash

    Sometimes after restarting or turning on the RPi5 I get this message:

    Code
    *** Error in mount_flash: mount_common: Could not mount UUID=0111-4635 ***
### Starting debugging shell for boot step: mount_flash… type exit to quit ###

    I've had the RPi5 for a week, and the SD card is also new. It was a fresh LibreELEC installation, and then I restored a backup from the RPi4. It worked fine for a few days until yesterday.

    This is what it looks like after I typed exit several times:

    I tried another SD card (an old 16GB SanDisk) and so far I don't have this error. It was a fresh install and a backup from the problematic SD card (a 64GB Kingston Canvas Go! Plus).

    LibreELEC 12.2.1, RPi5 4GB

    If the partition UUID's detected do not match the value in cmdline.txt or are not readable for some reason, boot fails. The partition data on the SD card can be corrupted through sudden power loss, e.g. after pulling the power cord, or because the card has some kind of physical or memory problem. Cards can and will fail at some point and there's never a guarantee on how long they last, and sadly these days purchasing name brands from online sources like Amazon doesn't guarantee you'll receive a genuine card instead of an indistinguishable but inferior quality copy.

    Quote from Da Flex

    Use GParted for scan and repair. This tool can leave bad blocks out during formatting.

    If the device has failing cells it's only a matter of time (and usually not much time) before more cells or the entire card fails.

    If it was just corrupted then reformat with any tool will fix. No need to jump through extra hoops with GParted.

    My main PC is running Windows 11.
    Windows didn't detect any errors on the SD card after formatting. I used this command:
    chkdsk g:

    "Windows has scanned the file system and found no problems.
    No further action is required."

    And after the first reboot, this error appeared again.
    Ok, back to SanDisk.
