The only place I can think of ATM is amigakit, pre-formatted for Amiga(!).  They even have 5.25" floppies - I'm impressed!  Maybe I'll order a lot for my C64. :)

have you tried HD disks and putting a piece of tape on the right side i think? this allows none high density drives to read them...i think!

Not all floppy drives like HD disks with the "HD hole" taped shut.

I remember, back in the old days when "swappers" existed, they pledged not to send them HD disks since they caused so much trouble.

Dunno the technical details behind it, but that's what I've heard.

Do you have a HD or a DD drive in your Amiga? If you have a DD, then you can even use HD floppies without taping the extra hole.
I have never ever had any issues with HD floppies on either a500, a600, a2000 or my a1200 and most of the HD floppies i have from the early 90s works just fine today, even though it has not been stored under the best conditions.

The (few) HD I have floppies work fine also. I've had errors on a couple, but they were usually cheap disks anyway.

I think I heard somewhere that the head magnets are more powerfull in a DD or HD drive than the other, not 100% sure though!

Hint:

read this page: http://en.wikipedia.org/wiki/Floppy_disk

Search for "stronger" and you'll find the tidbit about magnetic head strength.

As for using HD floppies in DD drives, I also _never_ had any problems on Amigas. And afterall: you have nothing to lose. If one doesn't work, just trash it. There is an overabundance of HD floppies today ( although not in a few years :-) )

Cheers!

I also use mostly HD disks since they are more easily available new. You only need to tape the whole if you are using them in an HD drive, to fool it into thinking it's a DD disk you've just inserted.

I did have quite a number of problems using HD instead of DD.....in a PC. Never on Amiga! Maybe the heads inside an Amiga drive are stronger than their PC equivalent, I don't know.

If you have a Commodore-era Amiga DD drive, you should be fine with HD disks. Later models had different drives and are known to have trouble now and again.

IIRC the 4000 came with an HD drive, so yes.
