file operations window hangs after completion of file transfer to FAT file system from ext4 file system

This happens on both of my systems. Currently I'm staring at a File Operations box displaying 758.6 MB of 759.0 MB for about 5 minutes. Here's the second system's uname:

$ uname -a
Linux hostname 3.2.0-030200rc5-generic #201112091935 SMP Sat Dec 10 00:36:07 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Status changed to 'Confirmed' because the bug affects multiple users.

Is also an issue for me. The progress bar goes straight to just shy of 100% then appears to hang. I believe it is something to do with writing to memory/cache, but I'm not expert and just want a progress bar that works reasonably well :-(

Linux coventry 3.5.0-27-generic #46-Ubuntu SMP Mon Mar 25 19:58:17 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

p.s. Try running the command "sync". Although this appears to hang to it will flush the cache and force it to write to the usb drive.

Have similar problem - progress bar going fast from 0% to 100% and disappear, but then I cannot eject usb drive.
Using ubuntu 13.04, have same problem in 12.10.

I'm also having the same issue as above in Ubuntu 13.04. The progress bar stops at 729,1 MB for file transfer of 6,6 GB. After a few minutes it tels me that the transfer will take 1 hour and 2 minutes (1,6 MB/sec) but nothing happens after that. After 15 minutes there is no update and the transfer doesn't seem to have progress at all so I have to cancel.

Trying to copy a 590M file from main drive to Kingston 16GB USB key.

It made it to 571M and just stuck. USB key is vfat, source is ext3.

.... lsb-release say Ubuntu 13.04 (Lubuntu)

Mounted USB drive directly to /mnt using root access - works fine.

Having a similar problem right now with Ubuntu 13.10 copying multiple files from mounted iso to usb stick (FAT) but got stuck at 2.6 out of 2.7 GB
Also my laptop started to lag and was almost unusable for some time during the copying but htop showed that memory usage is around 50% and CPU usage for all 8 Threads (4 Cores) never higher than 5-10% but the load average still goes up to 9.25

I just wanted to add that I am experiencing the same issue but with an external drive that I formatted ext4. There doesn't seem to be any consistency to when it happens, sometimes after a few gb have copied and sometimes after only a few mb. Only way out for me seems to be a hard reboot.

I have seen this. Could it not be a duplicate of 1001579 though?

It seems like after a couple minutes the progress bar dialogue box dissapears and the copy succeeds. I wonder if it is an issue with the display bar... or maybe ubuntu running some sort of check-sum. Ubuntu 12.04, copying from NTFS to FAT.

I did some research and this is a duplicate of: https://bugs.launchpad.net/bugs/1001579

Also it's not a nautilus problem, it's the kernel and how it transfers files.

You can mount the drive you want to write to with the -o sync option and that will write all data directly to the drive, so that the file reporting is accurate, though it is slower and can cause premature ageing in solid state devices.

Still affecting: 3.13.0-33-generic (Ubuntu 14.04)

    This is Happening in Ubuntu 14.04 3.13.0-107-generic
 file Operations Window Stays open a long time gets to 628.4 of 629.1
  Finally file operation ends after 4-5 minutes

This is still happening in 16.04LTS.

This issue still exist in 18.04LTS.its quite difficult to copy large file to usb
