Best practice
Use "had not forgotten" to emphasize the continuous state of remembering something, especially when contrasting it with forgetting. For example, "Despite the years, she "had not forgotten" the promise she made".
Common error
Avoid using "had not forgotten" when a simple past tense is more appropriate. "Didn't forget" is often sufficient if the emphasis on past perfect continuous isn't necessary. Instead of: "She "had not forgotten" to buy milk yesterday", say: "She didn't forget to buy milk yesterday".
