  • Copying a large file

    From Doug Laidlaw@2:250/1 to All on Sun Apr 24 11:42:06 2022
    I am trying to copy a file of about 3.5 GB from my Downloads directory
    to a mini (phone-type) SD with plenty of room. It always fails, with
    no error message.

    The "ulimit -S" command shows "unlimited." I seem to recall something
    about a maximum size of 2 GB.

    Any suggestions, please, or further info required?

    Sounds like a dose file size limit.

    What is the filesystem on the SD? From Wikipedia


    File system Maximum size[a]
    APFS 8 EB
    exFAT 16 EB
    FAT12 16 MB (4 KB clusters) or 32 MB (8 KB clusters)
    FAT16B 2 GB (without LFS) or 4 GB (with LFS)
    FAT32 4 GB
    HFS 2 GB
    HFS+ 8 EB
    HPFS 2 GB
    NTFS 16 EB

    It sounds like you have either Fat16 or HPFS
    EB-Exabyte= 1000000000 GB
    Ie, a hell of a lot larger than any SD. You could use FAT32 or exFAT
    instead if you really want compatibility with Windows.

    I have formatted the target to be NTFS, because it is a Windows system
    for the Raspberry Pi. According to Bill's list, any FS would allow it.

    I have a rpi 4b running Mageia 8. On it ...
    $ blkid /dev/mmcblk0*
    /dev/mmcblk0p1: LABEL_FATBOOT="M8RPI4EFI" LABEL="M8RPI4EFI" UUID="96AA-E132" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="261ea400-01"

    I also have an sd card with Raspbian os (which is based on debian linux). With it
    plugged into my desktop system ...
    # blkid /dev/sdf*
    /dev/sdf: PTUUID="000b624d" PTTYPE="dos"
    /dev/sdf1: LABEL_FATBOOT="RECOVERY" LABEL="RECOVERY" UUID="9AE3-8BA0" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="000b624d-01"

    So no windows system involved.

    What model of Raspberry Pi are you using? Where did you get a windows image file for it?

    Thanks, Dave. I have a Pi400,and the initial setup is virtually
    identical to yours. On separate SSDs, I have Manjaro and Ubuntu, which function tolerably well.

    The question of Windows is apparently "iffy." Originally, it was said
    to be impossible, but now, it seems, Win11 is usable, but not Win10.
    That struck me as odd, especially since the CLI method below seems to
    install Win 10 then upgrade it to Win 11. At https://www.worproject.ml,
    there is a link to a script for Ubuntu, and I have Mint, but the script
    seems to be out-of-date. After a couple of failures, I opted for a command-line approach, using "How to Install from other OSes" from the
    above site. It worked well until now, and I should possibly seek help
    there, but this error sounds more basic. In switching directories, the command "getcwd" often fails to find the parent directory or even the
    current directory. That may be behind the original error message I
    quoted. I have reached the limit of my knowledge.

    That sounds like a problem with the sd card. First try re-seating the sd card. Try using another card. If that doesn't help, try cleaning the contacts on the card and reader.

    I would consider an inability to run Windows to be a valuable "feature."

    Even if you must use Windows surely running it on a Virtual Machine
    with limited connectivity to the Internet is preferable to an
    installation to your fixed disk...

    A raspberry pi boots, and normally runs from an sd card. It doesn't have enough ram, speed, etc. to support VirtualBox. Mageia doesn't even build it for the aarch64 architecture.

    As each os is installed on separate sd cards, there's no additional risk other then what's normal when using any m$ software. One os cannot access an other os's
    files, since there is only one sd card reader (unless you also add a usb connected
    sd card reader).

    I have an rpi 4b with 4GB ram, using 32 GB sd cards. I was expecting it to run very slowly compared to my desktop system. For large file operations, it is slower,
    but normal application usage is reasonably close to the same speed.

    I used the raspberry os to confirm it works, and now use Mageia 8 on it.
    On that system, running Mageia 8 with kde plasma, primarily for running konversation
    and firefox ...
