You'll most likely find that they've all got attached header
or trailing bytes, or both. Otherwise the images are fine.
The same thing happens to images on my FTP site when folks
attempt to upload directly to download folders, rather than
to my specified upload folder.

maybe you can shed some light at what i'm actually looking at and how images work in general.

i an using text wrangler to get the hex dump of the images.
it groups the resultant text into "pages" ideally from $00000000 to $00022f00
with a break every 256 bytes. so you see a chunk 16 bytes wide by 16 bytes long,
it's just like 'disk fixer' of old.

for example, if i look at $00011b00 to $00011bff, is this the image of disk track $11 sector $b?
and does adt put this on that track $11 sector $b verbatim?

thanks,
