Hi,

If you do a simple test on the disk:

dd if=3D/dev/urandom of=3Dtest.img bs=3D65536 count=3D16

cat test.img > /dev/daX

dd if=3D/dev/daX of=3Dtest_rb.img bs=3D65536 count=3D16

diff test.img test_rb.img

The only problem I can see is that there is something wrong with the cache=
=20
invalidate/flush instruction wrappers on the sparc.

If you need, umass debugging:

sysctl hw.usb.umass.debug=3D-1
