The expression “feels like a blank with his hard drive wiped clean” is a metaphorical way of describing a person who is feeling empty or devoid of memories, emotions, or thoughts, similar to a computer's hard drive that has been erased. In literature and psychology, this feeling may be related to experiences of trauma, amnesia, or other conditions that impact a person's mental state.
