Many people report that they format fine but they don't retain their data as long as genuine DD disks. The theory makes sense (HD media need a higher field strength from the heads than DD media), but I've yet to see proof of it...

As an experiment, I've dug out a few floppies that were supplied on HD disks with the hole filled in (hard drive prep disks from Wizard Developments in 1997 or so). They haven't been touched since then, and I've tried two of them in my A1200 and both read 100% perfectly. So they're probably safe for a few years anyway...
