Hi Steve,
it was my first impression, that MDR got only big blocks, but you are
right, there are all sizes used. Now that I have looked more carefully,
I see some inconsistency. MDR img has always the same structure, I would
suspect, that block size increase with file size, but it is not true.
See list of my files sorted by img size:
File: SAmTopo_mdr.img, length 176291840
fat: 400h - 600h - 6200h, block 16384
File: SAmOTBR_mdr.img, length 113917952
fat: 400h - 600h - 7C00h, block 8192
File: AfricaHR_mdr.img, length 56901632

File: AfricaSE_mdr.img, length 4153344
fat: 400h - 600h - 1A00h, block 2048
File: AfricaSW_mdr.img, length 3403776
fat: 400h - 600h - 1000h, block 4096
File: AfricaNE_mdr.img, length 2904064
fat: 400h - 600h - E00h, block 4096
Probably something unimportant, but a bit surprising.
