Abandon ye fears and panic yet not as thou hast discovered the tapestry
staring thy in the face!

I solved this problem, finally.  Out of random luck, the first 2 1.44M and
singular 800K disks I tried failed a format, despite the fact I could read
*every* single block from the disks before and after a failed format.

I tried two more 1.44MB disks and they formmatted beautifully.  Apparently
SuperDrives are quite finicky about formmatting older (used) disks!

Fancy Trick No. 7:

Format a DD disk 720K with a PC.  Copy the first 64 blocks from an 800K
ProDOS formmatted disk onto the 720K disk using your Apple II.  I used
ProBlock for this purpose.  Next, "delete" the disk using Copy II+ and
behold as exactly 1440 blocks are free for ProDOS use!

I'm not certain what possibilities this holds, but it looks like with
careful programming, one might be able to read and write PC 1.44MB and
720K disks for file transfers...
