Nautilus/Thunar file copy progress bar is not accurate.

Hey Guys,

I have posted this under 'Newbie Corner' because I'm really not sure where this should go. I am using Gnome 3.6 with GNOME Shell. When I copy a large file from one device to another (say, my SSD to a USB flash drive) I get the copy dialog box with the progress bar. This progress bar jumps to about 98%-99% and stays until the file is finished writing to the disk. So, basically, the progress indicator is useless for determining an ETA which is bothersome when copying large (or many) files. I see the same behavior with Thunar and Nautilus so I suspect the file manager is not the culprit here. I am not looking for a workaround, files are still copying fine and if I *really* need an accurate progress indicator I can copy via terminal but it would be really nice if I can get this working correctly in the GUI too.

Thanks.

I have the same problem. If I copy something to USB/SSD the indicator is not accurate but when I copy something to a HDD then it works. I do not know how to search for this problem, so duckduckgo brought me here. Maybe someone has a hint.

What are the mount options for the USB / SSD? Do you mean an internal SSD?
What filesystem?

The settings in my /etc/fstab are:
/dev/sdb2               /               ext4            rw,relatime,data=ordered        0 1

I have the same issue with automounted (XFCE) SD card. I believe this started when I changed to SSD drive and noop I/O scheduler, but not entirely sure about it.

I already have flush options, it makes the progress bar stay up until all is flushed. The issue here is inaccuracy of the progress bar. I can of course use sync, but that will both slow down I/O and shorten lifetime of the device. From mount's man page:

       sync   All I/O to the filesystem should be done synchronously. In case of media with limited number of write cycles (e.g. some flash drives) "sync" may cause life-cycle shortening.

I tried rsync -a --progress and it suffer from the same issues.

I don't think there is a way to fix the "inaccuracy" of the progress bar. I can only suggest that you run sync after any file operation to your USB drive to make it is completed.
