[Utilities] [SOLVED] Having weird problem with coping files to a usb drive ...

[Kumann]

When copying text files with the overwrite option the process runs okay and the files look okay having good sizes.
I then remove the usb drive and when I re-insert the usb drive the file sizes are zero.

If I delete the files on the usb drive first and then copy the files, not using the overwrite option, the files look okay having good sizes.
When I re-insert the usb drive the file sizes are okay.

I have used a few usb drives and this issue happens with all of them.
I do not have this problem with other distros.

I spent three weeks trying out two dozen distros. I like Kubuntu the best.

Any ideas what the problem could be?
Any help would be appreciated.
Thanks in advance

You need to ensure that write operations to externally connected storage devices have actually completed before you unplug the device. Using Dolphin, just right-click on the device name and select Safely Remove. When the action finishes, you can then remove the device.

Issue still exists.
After copies are done a message box shows in the lower right corner of the screen stating copy is finished.
I still have to delete the files first before doing a copy ... I can live with that.

Strange…
Which version of Kubuntu do you use?
Which file system do your USB drives have (ext4, FAT32, exFAT, NTFS, …)?

It is lying, or rather is mistaken. The copy is not finished until the write cache is flushed, which can take minutes.

Only by clicking the "safely remove" thingy and it completes can you be sure everything is written.

Being one who denies that patience is a virtue, I often start a system monitor in which I've configured a page that shows I/O, and it's clear from that when writing stops.

I'll use the "safely remove" thingy from now on. Thanks.
