Airflow through a hard drive

[califauna]

Hi all,

Is there airflow through a hard drive when it is spinning? I assume so because they have filters, but judging by the amount of time it takes for the filters for my PC case to block up completely, this leaves me wondering why they dont get blocked up and need cleaning or changing.

Cheers.

commonly not necesary flow but in some contitions of temperature humidity presure, is necesari airflow

Thanks.

Is this constant? If so why dont the filters need changing?

the presure makes airflow whe neccesary.
If there is a lot of presure then air flow needed
if airflow not posible heads problems

Ah yes. I guess that pressure is needed to create the air cushion for the heads.

What would the airflow in and out be under normal atmospheric pressure though -minimal, or zero?
