I will take your suggestion and try another usb key. 

I tried two different USB keys that could transfer 156 MB easily to
other XO's. I only recorded that one failed consistently at 29 MB. I
didn't record at which point the other USB key failed.

I will try another USB key today to test it out.

I can see about sending it to you.
