When I copy files using nautilus, most recently from a NTFS external hdd to a FAT32 usb drive, the system crawls to a stop. Everything, even TTY login is affected. It's impossible to use the machine. I have a new computer, 3rd gen i7, 6 gigs of RAM, and I feel like I shouldn't be having this issue. Has to be a bug. Often times the destinations, as I said above, are both external. My OS is installed on a SSD, and I have a second internal HDD. Copying from these seems fine.
Running Ubuntu 13.10, clean install, 64-bit, fully updated.
Any help is appreciated.
