100gb+ file copy problem

[Moltke]

I have 1tb external HDD with exfat format . exfat using because I have windows 10 & macos laptop.
this format best way to communicate with all OS. But when I copy more that 100gb file
 movie, document, picture folders on LL5 ,  my touchpad mouse complete hang , I'm not able to open
any single window until finish copying. that's problem I never face with windows and macos. so I
search google . find some solution in ubuntu site . add few lines like this in /etc/sysctl.conf

vm.swappiness=10
vm.dirty_background_ratio=1
vm.dirty_ratio=2

restart computer and again I try to copy 60gb+ file to LL 5, same problem again. but when I put back
all file to my external HDD , touchpad works well , I can work side by side with copying.
I think maybe exfat file system problem . If I completely make ext4 file system to my external HDD
do it make same problem when coping ? If anyone know, please give me guide . why large file copy problem ?

What kernel version/versions is/are installed in LL? Open a terminal and type

Code: [Select]

uname -r to find out. Newest kernel versions, like 5.7 are supposed to handle exfat format better or at least that's what I've read https://betanews.com/2020/03/09/linux-kernel-5-7-exfat-driver/  You could try installing that one and see if that helps somehow

Code: [Select]

sudo apt-get update && sudo apt-get install linux-headers-linuxlite-5.7.0 linux-image-linuxlite-5.7.0 -y  read here for more info https://www.linuxliteos.com/forums/linux-lite-software-development/linux-lite-kernel/msg52097/#msg52097 Linux Lite kernel 5.8 is available as well https://www.linuxliteos.com/forums/linux-lite-software-development/linux-lite-kernel/msg53192/#msg53192

Code: [Select]

sudo apt-get update && sudo apt-get install linux-headers-linuxlite-5.8.0 linux-image-linuxlite-5.8.0 -y
Hope this helps!
