Please provide more details:
1. Is it on ZIF or in circuit programming?
2. What is the exact error message?
3. What means "not work every time"?
4. Did you try to use slower speed?

Did you erase the chip and do a blank check?

Yes,I tried to delete before write but information still remaining.
I managed to write 5 pieces but I have a lot of flash written.
Last ten attempts were failed.

It seems this chip is unable to be erased. It is possible that the chip is a bad chip.

I've managed to write 5 chips (w2tx32) after several failed attempts; I could not find a solution to have successful flashing each time.

The bin file is written without errors, but at read on the chip its still the initial information before the write

the average flashing time is around 20 mins on max speed

The chip must be erased before can be correctly programmed new data.
So, use the slow speed to repeat the erase untill it is erased.
Change to normal speed for writting.
