Just do verify again after it fails and see if it fails at same address.

The write will do the verify at same time.

If the verification fails at different address, then I just guess the write is OK. Only some thing wring the verification.

Try to reposition the chip in the ZIF socket and make sure all pins are well contacted.

Try to verify it with different speed.
