Does it simply fail?  Or does it corrupt?

In my Windows experience, if you try to write data past ~128GiB and
you don't have LBA48 support you get a wraparound effect that causes
corruption of the data below ~128GiB.  I've seen it happen several
times under Win2K in particular.

It will probably wrap and corrupt data.  The driver is already marked
HIGHLY EXPERIMENTAL.  Do you think we need bigger hammer

Probably if the driver has set the no lba48 flag and the drive is > 128GB
we need to clip the reported size of the volume and/or print a message
and skip it
