I have run into it with Ubuntu 18.04.1 x64 also. I have a completely separate drive and Windows system in the same computer and Windows, dare I say it, has no problem and is quick. My data files that fail are 400-500MB and they freeze after about 200MB of transfer when copy from a 32GB SanDisk Ultra (80MB/s) SD card. But success with Windows tells me I don't have a hardware problem.
This bug is now more than 3 years old. Like #78, I am disappointed. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1208993 Title: Ubuntu slows down and hangs while copying file from/to USB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1208993/+subscriptions -- desktop-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
