I have a Sparrow + Jade combo. My keys have always remained offline and have never been on my old laptop. This is why I don’t understand the destroy the drive answers I’m getting. My current keys are secure and offline. Yes, if the drive was restored, they could find the public address I sent my stack to but like you said, they wouldn’t have access to my keys.

Destroying the drive is always the answer if you have sensitive information on it. I suppose you just need to decide how sensitive you think your xpub is, since it doxxes the size of your stack, which could make you a target.
Anyone who recovered your xpub from that drive would know exactly how much Bitcoin you have associated with the private key on your Jade, and they would know that you have a hardware wallet, since the keys were not on the laptop. That would give them a significant amount of information to go on if they decided it was worth breaking in to find your hardware wallet.
That's without taking into consideration any other sensitive data you may have had on your laptop that hasn't been a part of this conversation already.
Hard drives aren't expensive. It's probably worth going full paranoid if you have any question about it and just replace the drive and let your buyer install whatever OS they want on the fresh drive.
Yep, then you don't have to worry anymore.
The small amount of fiat I’d get for my old laptop is not worth sacrificing my peace of mind and potentially doxxing myself and my stack in the worst case scenario. Appreciate your insight as always my friend!
