iPod iPod overheating

[Ja Di ksw]

If an iPod (iPod in issue is a 3rd Gen) overheats, will it erase all of its data? I ask because I left my iPod at home when I left for the weekend, it was very hot at home, and when I came back it works fine (has the newest OS on it still) but is blank. I don't know if this is something that happened due to heat, or if my roommate used it and erased it, in which case I will have to hurt him severly as I was using it as an external HD for some things which are now gone and can't be replaced. Do any of you know a way to recover files that were deleted from it? The HD may have been reformated, I don't know, though wouldn't it have gone back to the factory installed OS?

Edit: the calendars are still there, but all my other external HD data and songs are gone . . . . . . .
Excuse me while I go find a large, blunt instrument.

It seems very unlikely to me that overheating would cause the iPod to erase if the unit still worked.

That's what I was thinking. It worked fine, and still had a charge. And I thought it was off. The day it says it was modified (under info) was a day after I had left, and I think if it had been playing that whole time it would have run out of battery before then.

I've left my third gen in a car for hours, and it gets a LOT hotter in a car than in a house... I really don't think heat can zero all your data 🙄
