A question/myth about HDDs

My old PC had the hard drive mounted vertically like this |

My new PC's case mounts in horizontally, like this __

Most computers do, the old one was a Hell-Piss.

My dad swears that once the hard drive has gotten used to a certain way of placement that moving it after a long period of time being in the other way will damage it over time. He says that I need to get a new harddrive.

Is there any truth to this? I have never heard anyone else say this, but it's my dad, so I thought I'd ask. Don't hesitate to disagree, I just want the truth

 

I declare that he is, infact, wrong.

 

That is what I am thinking. He said that once he moved his HDD's position and 3 months later it crashed. I think it was just a coincidence, but he says that is why.

There is no logic behind it, anyway.

 

I agree with Kodo! I have an old 13 gig Maxtor hard drive that I have swapped in and out of systems, mounted both vertical and horizontal, reformatted several times, am still using and it is doing fine. Besides when a hard drive wears it will definitely need replacement. The only things to wear are the drive heads from coming in to contact with the disks, the motor going out, and the printed circuit card going bad.
