Not converting disk images created with CiderPress or AppleCommander

[nerun]

Running Python 3.12.4.

1. Create a ProDOS disk with CiderPress 4.1.1 or AppleCommander 1.9.0
2. Execute: ./po2dsk.py test.po
3. Check in Linux with command "file":

$ file test*                         
test.dsk: Apple ProDOS Image, Volume /NEW.DISK, 280 Blocks
test.po:  Apple ProDOS Image, Volume /NEW.DISK, 280 Blocks

Both files are still ProDOS, but they are different:

$ sha1sum test*
aa6797610379f37f66c34680429802dc50e1bc40  test.dsk
3b03054b88b2d4b7bde1db247476e6511c605798  test.po

Addendum

I decided to test with CiderPress 2 command line utility for Linux to list content and check both files:

$ ./cp2 v test.po   
File: test.po
Disk image (Unadorned, order=pdos/blk) - 140KB ProDOS "NEWDISK", 273 blocks free
Type Auxtyp Modified          Length  Storage *Name                             
---- ------ --------------- -------- -------- ----------------------------------

$ ./cp2 v test.dsk
File: test.dsk
Disk image (Unadorned, order=dos/sect) - 140KB ProDOS "NEWDISK", 273 blocks free
Type Auxtyp Modified          Length  Storage *Name                             
---- ------ --------------- -------- -------- ----------------------------------

We can see here that conversion is PARTIAL. Disk is now order=dos/sect, but it's still ProDOS "NEWDISK", 273 blocks free as you can see.

Here a test in a DOS ordered disk:

$ ./cp2/cp2 v test.dsk           
File: test.dsk
Disk image (Unadorned, order=dos/sect) - 140KB DOS 3.3 Vol 254, 528 sectors free
Type Auxtyp Modified          Length  Storage *Name                             
---- ------ --------------- -------- -------- ----------------------------------

Info after 140KB is different: DOS 3.3 Vol 254, 528 sectors free.
