Is it normal for a read to produce FF's through the first 15 or so rows of data and then show what looks like normal data after that? I've tried every device with 29F200 in it and get the same result every time. Using a GQ-4x4.

It is possible. Check chip ID. If you can get chip ID correctly, then most likely those data are correct.
