Not baking, but I've recovered data from spinning hard drives after freezing them, on a couple of occasions. The last one required keeping it in a cooler full of ice, because the data transfer was so slow that it would stop once thawed.
- artifact_44 7y agofreezing helps solidify and congeal the grease that degrades and becomes stickier over time and causes the drive mechanisms to stop spinning or blocks the seeking heads. As the drive heats up again, that degraded grease becomes a sticky goop again and gums up the drive. Heating devices to fix them is a form of "reflowing" where you're getting the solder on the board close to its melting point, helping the solder 'reflow' into the cracks that have formed between its component contacts, via thermal or mechanical stress over time.

- krallja 7y agoIf you get grease into your garbage disposal grinder, I’ve heard you should use cold water to get it to congeal so the grinder can break it up and it will continue flowing once it’s in the drain. If you use warm water, it might flow, but only long enough to then solidify on your drainpipes. Maybe something similar is happening on the hard drive: sticky is too viscous to flow at full speed, but solid just breaks apart and dances around on the platters while the heads can make contact with the magnetic media.
