why does my USB media transfer stop copying?

Hi
I have a rooted galaxy s5 with the Omega lollipop rom. And recently whenever I try to use usb media transfer it stops half way and gives an error saying it is not able to copy any more and stops. Even if I try to restart the process manually it gives the same error unless I Uninstall the driver and install I again by plugging it in.
Is there a way to fix this? Please help??
