I've used HD floppies with "OK" results, they work but I've found there are more instances of errors, disks that need to be written to twice, etc.
Where as the DS/DD disks from 15+ years ago (stored in the same boxes) STILL have 90% or more readable.
I fired up a bunch of my old Amiga floppies a few weeks back, and fortunately, most of them seem to be fine as well. (The C64 disks were OK as of about 3 years ago.) I picked up a bunch of (unwanted) floppies recently, they were stored properly but came from a humid environment. Interestingly, about 50% of the ones I tried were junk, couldn't even be formatted without errors.
BTW -- If anyone needs a good source for DD floppies, the
Diskette Connection are a great bunch to deal with. (The Imation brand floppies they sell are made in the US, which is kind of cool to see these days.)
