You can edit the Disk.info with the IconEditor.  One warning though.
If you copy your new Disk.info to another disk, reboot before trying
to reposition the drawers and icons on the disk.  Otherwise, some type
of system confusion between what's ON the disk and what the foreign
Disk.info contains can cause files and drawers to disappear in a puff
of smoke when you attempt to re-arrange them.  Rebooting and the subsequent
loadwb seem to remove the confusion.  (That all sounds real technical, eh?)

Note that changing a disk's Disk.info will NOT change what picture FORMAT
installs on a disk.  The plain vanilla disk and trashcan images are
hardcoded in the Format command.  If you want to play around and you have
data for an replacement image of the same size, you could use a hex file
editor and change the image bits in Format.  I don't have time to look
for them but this should help you find them:

UWORD diskBits[] = {
   0x0000,0x0000,0x3FFC,0x3F00,0x3FFC,0x3FC0,0x3FFC,0x3FF0,
   (6 more lines of data, then last line:)
   0xC000,0x0003,0xC000,0x0003,0xC000,0x0003,0xFFFF,0xFFFF };

UWORD trashCanBits[] = {
   0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,
   0x0000,0x3FFF,0xFFFF,0xFFF0,0x3FFF,0xFFFF,0xFFF0,0x3FFF,
   (9 more lines of data, then last line:)
   0xFFFF,0xFFFC,0xFFFF,0xFFFF,0xFFFC,0x3FFF,0xFFFF,0xFFF0 };

(Note - If you want to convert an Icon you've drawn to hex data, you
 can use my Icon2C program on one of the recent Fish Disks)

No.  WorkBench wants (and possibly requires) a Trashcan directory.
If you initiated the Format from Workbench, it assumes the disk will
be used in the Workbench environment and places a Trashcan on it.
