I recently installed a new Samsung 840EVO 250GB SSD into my HP Pavillion dv6-6120us. Only about 100GB of the old drive was being used. I first cloned my hard drive using Acronis True Image 2014. Everything went fine...the laptop now fires up in about 1/10th of the time. Programs open quickly and everything is working great except I frequently get a message the my RECOVERY (D:) drive is full. When I try the disk cleanup tool there are no files to clean up. I have read on various forums that this is not a problem since the drive is not used, and I wouldn't bother with it except for that pesky message that comes up (it usually come up after I first reboot, but can pop up at any time). Any ideas? Thanks in advance for your help.
