 we test it`s ok.
Do you mean that the read result is difference by using differect version software?
you can use compare to check if the data change or not.

 Differences between 4.5.1(2012-11-07).bin and 4.6.1(2013-02-20).bin >>> Last 2 lines (config), its no problem.
Differences between 4.6.1(2013-02-20).bin and 4.6.2(12-7-2013).bin (current version):
version 2013-02-20, area 190000h-1DFFF8h ->> readable ASCII symbols
I read chip- ok, verify - fail, compare ok!
version 2013-07-12, area 190000h-1DFFF8h ->> 0FFh
I read chip- ok, verify - ok, compare ok!
---
I don"t think that chip is bad. Digital foto frame work fine...

 I have tested 4.5.1 and 4.6.1,you are right.
They both have read bug, but program and verify are reliable.
Latest software 4.6.2 has corrected it.
plis use new software if possible.thanks for you detail replay.

 I have test on other programmers (thanks my friends).
VP790 + 4.6.2 (2013-06-18) fw 19 -> read ok
UPA v3 build 0.14 read as 25VF016B -> read ok!
Labprog+ -> read ID - fail, test canceled
SPIFlash -> read ok
Finally test on my VP990: erase, programm, verify, compare .
Soft 4.6.2 2013-07-11 is ok.
Thanks.
