If they're mroe than 512M (or is it 1024), don't mount them at all.  They'll
eat you alive - and your system.  I suspect that the msdosfs code must
be scribbling on the disk cache buffers.  When you problem hits, it'll
also attack disks thare are on a different controller !

I've *never* had a problem w/ slices of 512M or less, but don't quote me
on that !
