Hi,
You might experiment with starting a streaming read
from one shell (e.g. with dd or ddpt) and while that
is underway, from another shell issue a
'sg_reset --device' and see what happens. If nothing then
try 'sg_reset --target'.
Aborting a single, long duration command from the user
space (and only that command, assuming other processes might
be using that disk) is not easy to do.
