Since I installed 11.10 I am unable to copy large files (say 1gb or more) to ANY usb drive that is formated as FAT. The file starts copying, but soon an error appears, saying
"Unable to Copy" . "Error splicing file: Input/output error".
I am able to do it via terminal, using the cp command. I use Gnome3, but the same error has happened in Unity as well.
Apparently it works if I format the USB drive as NTFS or EXT3, EXT4. But, for many appliances, FAT is necessary.
The problem is also not with the USB port, because it works under Windows.
It did not happen before, when I had 10.04 installed.
