The factory image partition is used to recover your Operating System in case of a major problem, with no other options. In essence it is used to reinstall the Operating System. Nothing else should be in that partition except the image of your Operating System. Due to errors, files may have been written to the drive inadvertently. I suggest that you go into the drive and delete everything that is not pertient to the actual reinstallation of the Operating System. You will be able to tell what is unnecessary by the dates that are shown. Any current dates can be deleted. Do not write to this partition, in the future. You can use another partition or DVDs or CDs to write files
I wish you luck.
D: is your recovery partition with little free space. Nothing should be written on it. It can, however, happen, that e.g. file backup writes data on it if you did not change the target volume. D: is the default volume for file backup. I suggest you go into "Computer", double click on D: and delete all files that are not part of the recovery partition. If you don't know which is which, take a snip and post the picture here. Then we can help you sort it out.
A volume must always have at least 10% of free space, else you get a "low space" condition. It then also turns red in "Computer".
Once this is fixed, you must make sure that D: stays clean - e.g. assign another media for file backup. That can be an external disk, a USB stick of sufficient size or the DVD R/W drive.
