hard drive question

I was talking to a computer illiterate friend last night who had been told that when a hard drive is too full all the time it can cause it physical damage. His friend had told him that it was due to more expansion and contraction of the hard drive . Does anyone know if this is true? I hadn't heard of that before and can't seem to find anything relating to it on the net. Thanks ,

Howdy,

there's a good reason why you haven't seen anything relating to it.....work it out.

 

You really need to find friends that have a clue.

 

Thanks , I thought so but I don't figure I know everything nor ever will . I really wanted some conformation before I told them this was wrong.

 

I always go to 'computer illiterate' folks for advice

You don't want to run with a packed HD, but it's got nothing to do with heat expansion.
