Thanks for the help. The no DMA setting worked.
The SanDisks are both labeled identically and have the same model
number SDCFB on the outside. The OS shows that not all is what it appears
the 'H' model is shown on the SanDisk web site as an Ultra II device, with
different lableling that what I have.
So unfortunately you never know what you're buying until after you have it
