    Lubuntu 20.04 - File manager hanging on transfer to external storage (SD card)

    Hi all,

    I thought I'd fixed this issue, but it has reared its head again.

    I've run through various fixes available online, mostly involving writing a dirty bytes setting to `/etc/sysctl.conf`

    The relevant part of my `/etc/sysctl.conf` looks like this

    ```
    ##################################
    # doing the "fix" for SD card transfer
    vm.dirty_background_ratio = 5
    vm.dirty_ratio = 10

    ```

    Am I missing something?

    I have no issues recently transferring data to MicroSD cards, so this is news to me.
    I use Krusader as my File Manager.
    My /etc/sysctl.conf has no settings.
    Looking around I found this explanation of vm.dirty_ratio .. re caching.

    I learn something every day.

    If you fsck the file system with it unmounted, is it clean and contiguous? Could be a bad file system on the card

    Output of fsck is:

    ```
    sudo fsck /dev/sdd1
    fsck from util-linux 2.34
    fsck.fat 4.1 (2017-01-24)
    /dev/sdd1: 104 files, 814087/965534 clusters
    ```

    Try:
    Code:
    sudo fsck /dev/sdd
    instead
