Do the heads on older drives hover closer or farther from the data
surface than on newer drives?
The higher the bit density, the lower the flying height of the heads. So
in general, modern drives fly the heads a lot lower than old ones.
I don;'t think you're going to get away with this on say, a 3.5" 80GByte
drive :-). But those are not the drives we're discussing here. For the
old 40MByte 5.25" units, etc, you will have a lot less problems.
I'd not use a car eir filter either. But I think the sort of filter used
in the demountable hard drives would be fine as an input filter on the
clean box.
