You can get away with playing fast and loose with media on 3.5"
drives, but there, the differences are much smaller.
Yes, the coercivity of 5.25" is not very forgiving! HD diskettes used for
360K tend to self-destruct rather soon.
Whereas the 600 Oersted V ~730 of 3.5" is arguably within range for
non-critical use.
However, I interpreted wht he was asking differently. I assumed that he
was asking whether he could get away with 360K reading and writing on 300
Oerstedt diskettes using an HD drive.
We are looking at two different issues entirely!
