Hello, I am trying to write my bin file to this blank MX25L6406 chip. I am able to read the old chip just fine. I have performed the blank check on the new chip (it passes fine). When attempting to write to the new chip it hangs up on write. I have tried another new eeprom with same results. I am using Windows 7. I am also using the external 9v supply source. I have also tried a different usb cable. I am using the ADP-081 adapter.

Change to another chip and try. Sometime the chip is bad. Also, try a slower speed.
