Step 6: Deleting the Scratches (Optional)
First is (if you haven't already) to select just the middle bar and deselect the HDD characters.
Grab the stamp tool (Its difficult to find on the tool bar) alt and click a place that doesn't contain a scratch on the center bar. Then like airbrushing, spray on the stamp. if you start seeing edges or lines while pasting, alt + click again on a different spot (away from edges and lines) and paste from where you stopped.
