as above I can only think a recent windows update has caused this , I now have a drive "I" of 500mb which windows keeps throwing out popups saying my drive is low on space, this is meant to be a hidden partition on the boot drive. I have been into disk management, and there is no option on this partition to remove the drive letter. I have also tried using diskpart, and this says the drive is hidden, I tried to change the drive letter to blank but this didn't work either, anyone got any ideas how I do this?
