linux-usb-file-copy-fix.md

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) | sudo tee /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) | sudo tee /proc/sys/vm/dirty_bytes

To revert the changes enter this in console

echo 0 | sudo tee /proc/sys/vm/dirty_background_bytes
echo 0 | sudo tee /proc/sys/vm/dirty_bytes
