For fist we noticed the interleave so it isn't easy to take a look onto the hexdump
The image is obviously mixed up, but another dump of the second disk shows the same schema, so I hope that the disk drive is identical with the original and will work in the real computer.


Here is a dump from the analysis:

Board revision B detected 
Found drive at select 1
Returning to track 0

Sector length 512
Data CRC: Polynomial 0xa00805 length 32 initial value 0x0
Selected head 4 found 0, last good head found 3
Read errors trying to determine sector numbering, results may be in error
