HD floppy disks didn't seem to last very long when used in Amiga (DD) floppy drives.  Is this a complete load of rubbish?

.


it's a complete load of rubbish
hd floppies can last as long as dd floppies
in fact there are not technical differences between them ..only a hole
to store the floppies of course a sealed box away from moisture
otherwise they can get fungus like cd and dvds

Longevity-wise, no, there's little to no difference, except that today the quality as a whole is quite a bit less in the manufacture due to their reduced popularity and sales.  For instance, old micro-disks had a dust jacket through the entire internal surface, whereas now there's just a single patch -- arguably this is less effective than the full jacket.

However, there are technical differences between the two.


yep I agree
 also today floppies quality is very lame...the plastic is bad and soft....and I imagine that the surface and oxide of the disk is bad quality as well

btw, in the link posted by psxphill says that there is a difference in the oxide coercivity ..660 vs 720 anyways this can be theory....in practice I never found differences...hd disks always worked fine in the amiga and last long......and nobody can affirm correctly which one last long

I always found pre-formatted 1.44MB disks would frequently failed to format right away on track 0. What I would do is DMS a disk image to it. After that it would reformat just fine. I have no idea about the longevity.



another way to format those pre-formatted 1.44mb disks is format first with no verify then reformat with verify
