Problem Disk free space is only 9% on drive F:.

---------
How big is your F: drive ,to me this indicates the drive is almost full ,maybe
and that would cause the copy error .check recycle bin maybe

No, not having enough free space does not cause a delayed write failure.

Check the S.M.A.R.T. status of your drive using a program such as HDtune, just in case it's on its way out. You should also schedule a complete chkdsk:
Start > Run > chkdsk F: /R /F
And then answer Y when it asks if you would like to schedule the check on the next boot. Then reboot.
