So I was coping some video files (All about 600MB big) to my usb thumb drive. When I was coping all 4 the same time, it got the first one done but when it started doing the second it crashed. I also tried coping them 1 by 1 but when I got 2 done then on the third one it crashed. I know it’s not problem with the video files.
Its a 32gb Kingston thumb drive with filesystem vfat and I don’t know how its mounted. Not giving any error codes just said that the application is not responding and do you wanna close it. And I just copied files on the Dolphin program (I don’t actually understand this question so I just answered it as I understood it). Also it started happening after I updated my system to the latest version (I used Sudo pacman -Syyu on terminal to do so).
I’ve had this happen but only about 3 times out of hundreds (my backup strategy is to just copy my files to a USB drive). I think it’s because I’m overloading my system by doing other things at the same time. It happens so little, and restarting the process copies the files anyway so I haven’t done any investigation.
Try to say “no” and wait. My guess is RAM gets filled with cache and it takes time to flush it because writing the files may be slow. To the system, this may appear as the program is hanging, but it may not be true.
To circumvent this in the future, you may set a lower threshold for the transfer cache by creating a file in /etc/sysctl.d/
personally i switched over to Thunar because ive had nothing but problems with Dolphin. For some reason it will use so much resources sitting idle sometimes that my cpus will jump up 20degrees Celcius. Not to mention the weird bug where you have to delete the session file to get it to start sometimes.
Dolphin is a SOLID file manager and by far the best one out there. That said first thing that should of been done is to reset the flash drive to default to see if that rectifies the issue. I find in this type of situation it’s usually the drive acting up. Run the below in your terminal replacing sdx with the name of your flash drive.
sudo shred -s $((2048*512)) -vzn0 /dev/sdx
run lsblk in your terminal to list your drives and partition to get the name of your flash drive for the above command.
