  • cannot read SD card

    From faeychild@2:250/1 to All on Sun Aug 23 00:35:50 2020


    I have a 64 Gig SD card used in Zetta security camera that I can no
    longer read in linux .
    I allowed Windows to format it through the camera app which has rendered
    it invisible to Linux
    The card is formatted to fat which Windows can read just fine but Linux doesn't see.

    Linux Gparted will hang if started up with the card plugged in

    Until the Windows format the card was readable by both systems.

    This is just a bit mysterious Typical weekend drama I fear :-|

    IIRC, gparted can not handle exfat file systems.

    Which version of Mageia?

    One option would be to erase the partition table on the card with
    "dd if=/dev/zero of=/dev/sdz bs=1M count=1". Make sure the right device is specified. Then you can create what ever type of file system you want with linux.

    Guessing you do not have any fat/vfat drivers installed.

    Go ahead and install fuse-exfat rpm, I would also install the
    exfatprogs rpm

    Just the exfatprogs, not fuse-exfat. As per https://bugs.mageia.org/show_bug.cgi?id=26396#c16 the fuse-exfat package should
    not be necessary since kernel-desktop-5.5.15-3.mga7-1-1.mga7

    The fuse-exfat package can still be installed, but should not be needed.

    exfatprogs has ...

    /usr/sbin/fsck.exfat
    /usr/sbin/mkfs.exfat
    /usr/sbin/tune.exfat

    The fuse-exfat package has a kernel module for exfat file systems, but there
    is now an exfat package included in the kernel, currently ... /usr/lib/modules/5.7.14-desktop-1.mga7/kernel/fs/exfat/exfat.ko.xz

    I have been using the linux most of the day which curtailed the
    investigation and switching mouse keyboard and video cable between the
    two boxes is a real drag.


    But this morning I had re set the camera with a 32Gig card not formatted
    by Windows I have just retrieved it and Linux can read the card/camera OK

    I have just attempted to read the card/camera with 32 Gig card in windows

    Plugged into :-
    The first USB socket does nothing
    The second socket declares that the camera is not plugged in
    The third socket declares that Windows has a problem and must gather
    data and then reboot..

    The 32 Gig card is still readable in linux - that's a complete switch

    The 64 Gig card can't be read and is not detected by linux

    I think Windows has trashed my 64 Gig card

    The problem is Windows It can' read any other card in reader either. Depending on which socket I use I either get nothing or " Windows has
    detected problem and must reboot"

    I may have to reinstall windows

    Pity about my SD card

    Right I am, in the middle of conflicting errors here. It all started ( seemingly) when I used the Windows camera widget to format the SD card
    in the camera.

    I will stop chasing ghosts and give up while I am ahead

    Sounds to me like the app did something proprietary to the format, with
    the express purpose of preventing outside tampering. It is, after all, a security camera, and if it is easily read it's not very secure.

    Ok The sad sequence of events is

    The little camera is about half the size of a cigarette packet and uses
    an SD card for storage. The manufactures config widget only works on Windows

    I decided to change the aspect to 1280-720 and increase resolution.

    I dragged out the Win box, changed over the mouse keyboard and monitor
    cables and plugged in the camera and changed setting. Then put the
    camera back under the eaves

    Later I took it down and plugged into Linux. There was nothing. NO video files. I wondered did I mess up the new config.

    So the Win box is reconnected and the camera plugged in. File explorer
    opens showing all the video files. And they play fine

    ....??

    I check the config anyway. It was fine

    So switch cables back to the Linux box, plug in the camera and see
    nothing except some DOT dat files.

    Then I plugged the SD into a card reader into Linux and it's still empty.

    I plugged the card reader back into Windows which told me there was a
    problem. It was gathering information and would reboot the computer.

    Nothing was found on the card

    So back to Linux which now failed to recognize a card at all. No USB
    device registered.

    A great darkness descended

    Sometime later after drying my eyes, I plugged a different SD card into
    the camera. This works just fine.

    I have been pwned by bizarre hardware failure and the evil spirits that
    live in the Windows box.

    I want to demolish blow up something

    I wonder if the sd card is one of the fake ones that claims to be much larger than what it really is, in which case once the card is full and continues to accept writes, it overwrites the start of the card including the partition table.

    Yep I am aware of them also

    This card has run for many months although I have never interrogated its capacity

    It is the usual bucket full of unknowns

    Did it fail unprovoked ?

    Did the manufacturers app break it during the format?

    The windows box is becoming a little flaky also. It was a motherboard
    that initially died running Linux and seemed to recover many months
    later when check over. So I put Win 10 on it

    Quite possible, since if it's a fake, it wasn't made by that manufacturer,
    and the manufacturer's app may stress the card more than regular formatting software does.

    that initially died running Linux and seemed to recover many months

    Linux is much better than windows at detecting faulty hardware. It will not
    run when that's found, in order to prevent people storing more data on
    hardware that's started to fail.

    I had a system like that. It wound up being a cpu heat problem.
    Pulled the cpu heat sync, cleaned out the 1/32 of aluminum paste, use
    a heat sink grease, and it had no more problems for years.

    It's a Sandisk and it's the only 64 Gig card I have. So, of course, that
    one fails



    The camera manufacturer makes a Win app and a Mac app and not a Web app

    And it usually just works

    I have still to fit my cooler and the amount of paste grease is always a dilemma.
    I should be as thin as possible and just fill the surface imperfections
    and that can't be seen with the heatsink fitted. You work blind

    My cooler comes with a compound called Mastergel Pro. That sound suspiciously like the cheapest shit they could bundle

    I also have another I purchased independently, called Arctic Silver.

    I think I prefer that one
