What happened?

When I create the ventoy U disk with the ventoy tool on Ubuntu system. I try to copy the ubuntu ISO, it will ok soon. But I could not eject the ventoy USB disk and the ISO md5 file is crash.

When you finish copy the ISO file. Open terminal and run sync command in the shell and then eject the USB. In Linux system, although it seems that the copy has finished, but some data is still in the memory cache and has not been flushed to the USB hardware.

Ok thanks, I have try the sync command yesterday night, but It cost too long time to finish the copy operation. I will try the method today.

Best Regards

It cost too long time to finish the copy operation.
It depends on the write speed of your USB stick. You should wait the sync command finish before you eject it.

Thanks a lot for ventory, I tried the way which you provide the guidance, and it was successful. I have an immature idea, is it possible to integrate th cp and sync command into the "ventroy" tool and provide a UI menu to use? Just provide another way to the general users.
