Thank you a lot, Alan. Information you've provided is really helpful for me.
I'VE GET THIS DEVICE WORKED.
Let me explain briefly:
This device has memory stick 64MB. But for unknown reason it reports 127MB
geometry (in Windows as well), contains 248832 sectors.
Then it reports of two 64MB (why?) partition. The first partition is formatted
correctly and has 64MB capacity (the real one).
Second partition is unformatted and seems to be unreal and buggy.
I've realized device crushes when Linux tries to read 8 last sectors (aren't
actually present).
So, I've just patched kernel scsi module to divide sectors amount on 2 and
change geometry to be 64MB.
So it works.
This solution is applicable for SonyEricsson K750i (R1N035) with 64MB Memory
Stick.
