Simple question, how do I determine the Sector Size value under properties?

Increments as follows:
Address: 0x13cb38000 - Sector: 0x22c6400
Address: 0x13cb40000 - Sector: 0x22c6800

Is Sector Size:

0x13cb38000 - 0x13cb40000 = 0x8000
or
0x22c6400 - 0x22c6800 = 0x400

I keep running into SanDisk images with plenty of data (80% or more full) using Sector Number Slow and the resulting image file has almost no data yet the sector numbers are well within the GB bounds limit.

Same as block size

With "jumps"
http://www.flash-extractor.com/manual/hex_editor/

But sector size usually have small numbers
0x1000, 0x2000, 0x8000..

So, set jump size = 0x800
Jump down
And look where sector number will change
Period with which "sector number" changes is sector size

May be wrong layout selected
And this is not sector number

Do you wait until save process complete on 100%?
If cancel before, image will have zeros in random places
