That's advisable, but as I said, if you can bulk-erase a floppy before writing it, you'll be fine. I use a VHS tape bulk eraser, but those things are getting to be pretty uncommon now.

I need to bulk erase the DS-DD disk before I can use it in a DS-HD drive? I'm a bit confused on that bit.
The bulk eraser is a bit old.the Realistic 44-210. It's old enough the box art shows someone erasing a reel and an 8-track.

That should do it.
The reason is that a 96 tpi drive writes a track only half as wide as a 48 tpi one (the kind the O1 has)--and you're writing every other track (double-stepping) So if you don't bulk-erase a DD disk before using it, the O1 drive head will also pick up the background "noise" between tracks and create read errors.

Okay, so I move Imagedisk and the disk images over to an AT&T PC 6300 which is fitted with a 360K double density drive.
I fire up Imagedisk and try to write:
...and that happens. It does nothing.

PC Compatibility issue, perhaps? Have you tried running Dave's test program?

The included drive test program?
Huh, well apparently failed on the first test.
So much for 100% compatibility.
