I'm sure that when dust gets between the head and the disk, it
makes a bit of oxide chip off due to friction.
For one thing, a floppy drive head is in contact with the media - it
doesn't fly. And thus it can't crash.
Now a lot of dust will increase head/disk wear, of course/

I did open up the disk housing (I almost called it an HDA) of an old
10Mbyte (I think, maybe 5 Mbyte) Syquest. This thing was very much like
a
winchester, but there was a recirculation filter
inside. So I guess it
was better than nothing.
Is this what you said earlier was the only undocumented part of your
AT? What do you use now?
Yep, and they still are. I've got a Seagate 1.3Gbyte drive here that's
very dead, and there is a little fliter inside the HDA at one corner. I
assume some of the air goes through it...
Also, newer drives spin faster, don't they? This would cause more
damage when a head goes too low.
Possibly higher density -> lower flying height -> more likely to crash
on
smal dust particles.
