Forest were beaten 5-0 by their rivals last season and Reid says that result is going to serve as motivation for the clash which takes place on Sunday at the City Ground.
"I suppose in a way, we owe them one. But if we are looking back at that team that played last time we met, we were missing a lot of our best players," he said to the Nottingham Post.
"When we had pretty much a full strength team, we beat them at our place last season."
"I think the one thing we could say for certain is that the score would not have been what it was, at Derby, had we had a full strength side when we played there."
"I would not read too much into that game, because they caught us at the right time."
Forest are a far different side from last season and will pose the Rams much more a threat when they meet.
Stuart Pearce's men are the early pace-setters in the Championship and are five points ahead of Derby, but they know they face their toughest challenge yet in the derby match.
Derby were tipped as promotion favourites before the season started and they have a side which oozes quality.
Last season it clearly posed too much of a threat to Forest, but the Reds have much more quality in their line-up this time around.
They bought well over the summer - bringing in the likes of Michail Antonio, Britt Assombalonga and Chris Burke - and their summer recruits seem to have kicked them on to the next level.
Their unbeaten start has encouraged fans that Forest could finally return to the top tier this season, after years of trying and, if they can beat Derby, confidence will rise further.
Reid is likely to be key to this, as the most creative figure in Pearce's squad, but he insists that the reliance on him hitting top form after the influx of attacking additions of the summer has helped him.
"I kind of feel as though the creative burden has been taken away a little bit, which is nice," he said.
"It is good to link play a little bit more; to move the ball about and use the lads who have a little bit more pace."
"We have a lot more creativity in the side than we did last season."
