Boki,
Is this by chance a 16bit Flash part? - is appears all your odd bytes are
corrupted.

If it is a a 16bit flash part then I have seen this behaviour before, it
occurrs during the write when you only test for the 'end of write' on the
high order byte status.

Any chance you can provide the flash part number?
