No, it's NOT the only non-block-oriented device. How about RAM:? Or networks?

But more to the point, it's the most common device out there: everyone's
got it and uses it at least for software installation. Most people use it
for everything.

It should be properly supported... and that means bad block handling
*somewhere*.

And, of course, turnabout is fair play. Just because it's the only device
that presents an imperfect volume to the FS, does that imply it always
will be?

I don't see how, if the driver or hardware "presents a flawless device" to
the filesystem, the filesystem should never map a block.

I can't use DiskSalv to recover *anything*. Well, that's not true... once I get
it to work it works well enough.

I'm pretty sure I'm up to date on it, but it frequently insists that the
output device is full... even when it's a freshly formatted floppy!

And what about hard disks... how do recover them???

Well, I can assume that we'll never see a FS that handles bad blocks.

How about a trackdisk.device that does?

You have to put it *somewhere*.

And enough of this "buy a hard disk" or "buy an Amiga 2000". If I had that
kind of disposable income I would have.
